MarsSeed [1] filed a deletion request for wire-desktop-appimage [2]:

Duplicate of repo package, not needed:

https://archlinux.org/packages/extra/any/wire-desktop/

This is an Electron-based application, so there is no benefit in using
this AppImage in a PKGBUILD. The repo version has the exact same
application code.

And repo verison is even better because it does not duplicate the
electron runtime, but depends on the relevant repo electron package.
