UMAP File Wont Load In Content Browser

I am trying to import a UMAP File to the Unreal Content Browser, I have copied and pasted it into the browser which comes up with an error “Failed to load … unknown extension”, I then went to the content browser folder through file explorer and pasted it there, still doesn’t show up on content browser in unreal. I have been researching and trying to find solutions nothing works. I saw one that says its a unfixable bug and hoping they are wrong. HELP ASAP

Thank you!
