Support custom URL scheme beyond-identity-endpoint in Qt Web

[klDen]

Currently, I'm using beyond-identity as MFA. After clicking on Connect in GlobalProtect-openconnect, it redirects me to a web page where normally it would attempt to open the URL scheme beyond-identity-endpoint:///. Unfortunately, I don't believe it's possible to specify the scheme at the moment (no pop-up notification to select application like Firefox). I believe the following links may be helpful for adding support for custom URL scheme :

• https://doc.qt.io/qt-6/qtwebengine-features.html#custom-schemes
• https://doc.qt.io/qt-6/qwebengineurlscheme.html
• https://doc.qt.io/qt-6/qtwebengine-features.html#web-notifications

Firefox

Chromium
