    Buttons can have as attributes:
    - "style" (one of Discord button styles),
    - "id" (arbitrary but required so bot can choose action based on it)
    - "action" (the action performed, either toggle-role:&lt;ID> for roles, toggle-role:&lt;GROUP>&lt;ID> for exclusive roles, or toggle-channel-access:&lt;ID>)
    - "url" (if it's an external link. "action" cannot co-exist with "url")
    - "disabled" (set to true to disable the button)
    - "row" (optionally, 0 to 4 row information)

    Buttons can have as inner tags:
    - "label" (for the actual text in the button)
    - "emoji" (if any emoji should be in the button)
