Google Drive comics greyed out

Hey guys! I just became a Panels user and was just giving it a try. Sadly I only have a 16Gb iPad and for that reason I became a Google One client to have some more storage for books and comics. Whenever I try to open my comics stored on Google Drive on Panels through the files app they are greyed out, I can’t add them to my library. The only way I can open them is to download them locally to my iPad but since I don’t have enough space it really isn’t an option. Anyone else having this problem?
