Change MUA (mail user agent) or application name when using OAuth

[forumforeign]

Hello.
I want to connect mailbox from office365 but, when I type OAuth2 credentials I see a windows "request approval" which tells "www.thunderbird.net" is not allow to access. I can't change setting from that side, but, if I change a useragent from Thunderbird side, like an "outlook" it will be passed.

general.useragent.override

doesn't influence to this OAuth2 window.
