While it is good to have somewhere to see the current installed version of the app, adding an update app area would improve workflow in many sectors, including personal installs.
I have recently found how to use WinGet to update the apps on my computer. WinGet already recognizes that Proton Pass (and other Proton apps) needs an update and attempts to update them. For me, WinGet fails to update Pass almost every time. A more secure option would be to open Pass and go to a "Check for Updates" section which would be coded to check a secure server and verify the app before installing over the existing app. This would remove the third-party apps possible insecurities and also streamline updates: currently I have to log in to the website; download the updated app; verify checksums; run the installers; verify the app runs; delete old installers.
