Steps to reproduce

1. Set up Slack as OIDC Identity Provider for Nextcloud server
2. Try to log in (see first screenshot)
3. Slack indicates that the browser is not supported (see second screenshot)

Expected behaviour

Slack should authenticate the user and route the user back to the Nextcloud instance in order to finalize the authentication process with OIDC.

Actual behaviour

After forwarding to the Identity Provider URL, the Slack website states that the used browser is not supported. In this case, the user-agent seems to be "Mozilla/5.0 (iOS) Nextcloud-iOS/7.0.4" (see first screenshot, also tested with 7.0.6)

Logs

(not applicable)

Reasoning or why should it be changed/implemented?

Slack argues that this is not a Slack issue but Nextcloud shall make use of a supported browser.

Environment data

iOS version: 7.0.6 (also tested with 7.0.4)

Nextcloud iOS app version: Nextcloud Matheria for iOS 7.0.6.1

Nextcloud version: 30.0.10

Please try #3996 and see if it fixes the issue, or wait for a new Testflight.

Unfortunately, this instance is not based on Slack anymore, so I am lacking a test environment.
