 Browser Tabs is a Windows Command Palette extension, not a standalone app. Its app-list entry is disabled intentionally because users launch it through Microsoft PowerToys Command Palette.

 Restricted capability explanation for `runFullTrust`:

-Browser Tabs declares runFullTrust because Command Palette extensions use an out-of-process COM server and packaged COM registration. The extension runs as a desktop Command Palette extension, enumerates local Chrome and Microsoft Edge window/tab UI Automation elements, and activates the selected local browser tab. It does not use runFullTrust to elevate privileges, install services, modify system settings, or access user files.
