Hi @Nida6025, when sharing a file from a third-party sharing service like Google Drive or Microsoft OneDrive. Follow the on-screen prompts to sign in to the third-party service and grant Zoom access.
These options may be disabled by account Admins, so available options may vary.
Alternatively, you can open the file in a web browser then share the browser window. For example, to share a Google Doc, open the Doc in Chrome, then share the Chrome window. The end result is the same as using the sharing options in the Files tab.
