"Error 403: disallowed_useragent" when trying to sign in to Dropbox to access Excel file

"Error 403: disallowed_useragent" when trying to sign in to Dropbox to access Excel file

Please help.

I'm using a Pixel 6 with Android version 12 updated 7/5/22.
I was trying to open an excel file on Dropbox with Excel.

It then brought me to this page saying "Sign in to Dropbox to link with Microsoft Office Integration" in the Excel app.

I chose "Sign in with Google" since that's how my Dropbox was setup.

After entering my email and password, it told me "You do not have any security keys registered for this account.", so I chose "Try another way".
Then I chose "Tap Yes on your phone or tablet", which then caused Google to send me a notification asking "Are you trying to sign in?"
I chose "Yes, that's me.", then the Authorization Error page showed up, with the following message:

Authorization Error
Error 403: disallowed_useragent

Sorry I don't know what happened, but when I tried the same thing today, it did not ask me what app to open the file with and directly opened it with Excel.
It asked me if I would like to link Dropbox to either Microsoft or Google (I didn't read carefully), then the file opened without much problem.
