Disable sticker suggestions across platforms

I understand automatically enabling Sticker Suggestions to inform users of its existence. With that said, I've had to manually disable Sticker Suggestions:

• on my Android phone, in-app
• on my Android tablet, in-app
• on my Android tablet, Brave browser
• on my laptop, Firefox browser
• on my laptop, Chrome browser
• on my laptop, Discord app

I'm hoping this is a bug that will be fixed soon.
