Page Revisions: How to delete

I’m working on a homepage from scratch and there are probably hundreds of revisions already.

How do I delete these “easily”? I don’t want to write sql to delete them from the database.

I tried a plugin but it only recognized versions/revisions of “posts” not pages.

I’ve done some post searchs that suggest I should have a Settings>>Revisions but I see no such option in WordPress
