This is a bit different from the attachment feature request.

This feature could work as follows:

• There is a directory dedicated to Proton Pass in Drive
• Inside this directory are other directories/folders, arbitrariliy named (e.g. identically to the login in PP or just an ID)
• In PP there is a new field type (e.g. "attachment")
• Adding this field opens a dialogue, so the user can upload a new file (which gets uploaded into that previously mentioned Drive folder)
• or maybe the user can even pick a file from Drive (which then gets copied/moved into that folder
• So when logging in, the user now can click on the display/eye icon which opens a preview of the file
• only specific filetypes that offer preview, e.g. jpeg, png, pdf, ...
