If anyone's looking for an up to date theme or CSS code for the newest discord UI updates, I made my own. :::}

/*You may remove or comment out any bit of code you want, if you would prefer to have certain buttons.*/

/*The code below removes the Sticker Picker button in the right of the chat box.*/
[class$="buttons"] div[aria-label="Open sticker picker"] {
    display: none;
}

/*The code below removes the GIF Picker button in the right of the chat box.*/
[class$="buttons"] div[aria-label="Open GIF picker"] {
    display: none;
}

/*The code below removes the Nitro Gift button in the right of the chat box.*/
[class$="buttons"] div[aria-label="Send a gift"] {
    display: none;
}

/*The code below removes the "Apps" button in the right of the chat box.*/
[class$="buttons"] div[aria-label="Apps"] {
    display: none;
}

/*The code below removes the "Apps" button in the bottom left user area, when in a voice call. You can also still access this if needed if you click into the voice call.*/
[class$="actionButtons"] button:nth-child(5) {
    display: none;
}

I updated them and and tweaked some for better UI experience and so they won't break as much

/* Hide unnecessary stuff */

/* Emoji, GIF and sticker button container (remove /* at beginning to delete all. All but main emoji button included below) */
/* [class$="buttons"] .expression-picker-chat-input-button:not(div[class*="vc-chatbar-button"]),

/* GIF button + removes empty space */
[class^="expression-picker-chat-input-button"]:has([aria-label="Open GIF picker"]),

/* Gift button in chat + removes empty space */
[class$="-container"]:has([aria-label="Send a gift"]),

/* All Gift buttons like shop, etc (leaves empty space in chat) */
/* [class$="buttons"] [aria-label="Send a gift"],

/* Vencord Stickers+ button */
/* div:has(> button > svg.vc-more-stickers-icon),

/* Server tags */
[class*="chipletContainer"],

/* App launcher button */
[class$="buttons"] .app-launcher-entrypoint,

/* Apps in VC (participants/screenshare screen) + removes empty space */
[class*="buttonContainer"]:has([aria-label*="Start an Activity"]),

/* Apps in VC (user panel) */
button[aria-describedby*="«ret»"],

[class*="upsell"],

[href="/activities"],

/* Big library button */
[href="/library"],

[href="/store"],

/* Big shop button */
[href="/shop"],

/* Big quest/mission button */
[href="/quest-home"],

/* Discovery button in server list */
[class*="tutorialContainer"] + [class*="listItem"],

/* Events list in server */
[class^="containerDefault_"]:has([data-list-item-id^="channels___upcoming-events"]),

/* Events in server */

{

}

@MichaelDavidGK the aria-describedby for apps in VC would change daily about a week ago, and be inconsistent naming schemes between devices. I don't trust that code remaining consistent anymore, so I specified the "child" in the actionButtons class to display none, and it worked consistently so far

@MichaelDavidGK

/* Gift button in chat + removes empty space */
[class$="-container"]:has([aria-label="Send a gift"]),

this line seems to break/remove the entire interface for me, could be that it interferes with themes (?).

@Swedishdogs

/* Gift button in chat + removes empty space */
[class$="-container"]:has([aria-label="Send a gift"]),

this line seems to break/remove the entire interface for me, could be that it interferes with themes (?).

Change it to this and it should work:
[class$="-container"]:has(> [aria-label="Send a gift"]),
