How do I upload a photo to Twitter from a Gallery folder?

[colink2]

Samsung s20 (same issue on other Android phones)
When adding a video to Twitter I can only find videos in my recent photos / media list.

Gallery Synced to OneDrive (same issue before syncing)

When I go into any folder, I only see jpg images.
The only way I can upload a video is to go to my OneDrive app, download, go back to twitter and upload from my Galley recent media.

How can I upload video to Twitter from a specific folder?

Any help with this would be appreciated
