Reddit - Add warning or block Video posting

Hello!,
This request was based on my experience with the Reddit API via dashboard.

Would we be able to get a warning banner, or outright block posting if we are posting a video to reddit?

Miki was able to advise via support that this is because the reddit api does not support videos, but new users (myself included) may not know this until AFTER it has failed for them.

Would be nice for user experience “Reddit does not support Video posting with external tools” or something.

Thanks!
