When trying to log in to zoom with SSO, zoom opens a link in a browser. Once I log in with my SSO provider, the browser tries to open an URI starting with zoomus://. It fails because the .desktop entry registers only x-scheme-handler/zoommtg but not x-scheme-handler/zoomus. Adding that manually and regenerating mime cache fixes the issue and SSO works correctly.
