How to find the URL which is being accessed when I try to download multiple files from OneDrive Web

Question

We have blocked access to all the URLs via Define a list of allowed URLs GPO.
When the User is selecting multiple files and clicking download nothing happens. It could be because it is trying to access a URL which needs to be allowed.
Expected behaviour
Multiple files should zip in file like OneDrive_1_07-06-2022 and download.

Please suggest how can I find which URL it may be trying to access.

Answer 1

Managed to fix the issue, using the Network tab of Developer tools in Edge.
Request was sent to the following URL - unblocked it in the GPO. Working fine so far.
