How do I delete recent images in adobe express mobile?

If you use Adobe Express on mobile, if you use an image to make a project, that image is stored in a sort of recent images gallery that appears whenever you open up add -> photos when making a project, this gallery also keeps images even after you deleted them from your phone's gallery

This is what I mean (I've deleted all the images here, btw):

How do you delete images from said "recent images gallery" (sorry, I don't know what they're called), I may or may not have used an image I didn't want accidentally and I want to delete it from the history or gallery or whatever
