Sticker

The name of a Discord entity: a user's or member's account name, a guild's name, a role/channel name, a bot's define-name. Registered on Skript's native Property.NAME, so the idiomatic "name of %x%" works without colliding. For a member's server nickname or display name, use "effective name".

The avatar/icon URL of a Discord entity: a user/member's avatar, a guild's icon, a sticker's image, an application's icon... Co-owned across every type that has one, so "avatar url of %x%" works on any of them. Always a string (the image URL).
