stickerpicker

Serve everything under web/ using your webserver of choice. Make sure not to serve the top-level data, as config.json and the Telethon session file contain sensitive data.
Type /devtools in chat. Other -> Explore account data in Element Web (not "room account data", must be the global one), edit the m.widgets account data event to have the following content:
```
{
    "stickerpicker": {
        "content": {
            "type": "m.stickerpicker",
            "url": "https://your.sticker.picker.url/?theme=$theme",
            "name": "Stickerpicker",
            "creatorUserId": "@you:matrix.server.name",
            "data": {}
        },
        "sender": "@you:matrix.server.name",
        "state_key": "stickerpicker",
        "type": "m.widget",
        "id": "stickerpicker"
    }
}
```
If you do not yet have a m.widgets event, simply create it with that content. You can also use the client-server API directly instead of using Element Web.

The theme=$theme query parameter will make the widget conform to Element's theme automatically. You can also use light, dark or black instead of $theme to always use a specific theme.

You can use https://maunium.net/stickers-demo/ as the URL to try out the picker without hosting the files yourself.
Open the sticker picker and enjoy the fast sticker picking experience.
