legal:ms365 plugin/mcp authentication error

[liston611]

When trying to authenticate the ms365 plugin for legal (potentially for other modules as well, but I haven't tried), the following error is thrown:
AADSTS9000411: The request is not properly formatted. The parameter 'prompt' is duplicated.

If I remove the first prompt parameter, I am able to select my MS account, but then receive another error:
AADSTS900971: No reply address provided.

Same for me about the 'prompt' duplication error. The URL is https://login.microsoftonline.com/common/oauth2/v2.0/authorize?prompt=select_account&{other_parameters}&prompt=consent

I manually removed the last &prompt=consent from URL, then succeeded to login.
