unable to upgrade zoom on Arch Linux

I’ve got zoom installed on my Arch box. When I start it, it shows me a window which states on the bottom Version: 3.5.374815.0324. The problem is, I don’t remember how I got this original version installed. I tried sudo pacman -R zoom which gives me error: target not found: zoom, the same with yay -R zoom. It also does not show up inder zoom -Q.

I downloaded the latest version from https://support.zoom.us/hc/en-us/articles/204206269-Installing-or-updating-Zoom-on-Linux#h_c0913442-0832-428d-aa15-b004b80cfafe and tried to install it with sudo pacman -U zoom_x86_64.pkg.tar.xz and while it first says:

loading packages...

looking for conflicting packages...

Packages (1) zoom-5.0.399860.0429-1

Total Installed Size:  150.29 MiB

:: Proceed with installation? [Y/n] 

, after confirmation with Y I get:

...

zoom: /usr/bin/zoom exists in filesystem

zoom: /usr/share/pixmaps/Zoom.png exists in filesystem
zoom: /usr/share/pixmaps/application-x-zoom.png exists in filesystem
Errors occurred, no packages were upgraded.

Hoe do I get these files overwritten and zoom upgraded to the newer version?

Update

I moved /opt/zoom/ to /opt/zoom~/ and a retried but got:

$ sudo pacman -U zoom_x86_64.pkg.tar.xz

upon which I moved each of these files like so:

$ sudo mv /usr/bin/zoom /usr/bin/zoom~
$ sudo mv /usr/share/applications/Zoom.desktop /usr/share/applications/Zoom.desktop~
$ sudo mv /usr/share/mime/packages/zoom.xml /usr/share/mime/packages/zoom.xml~
$ sudo mv /usr/share/pixmaps/Zoom.png /usr/share/pixmaps/Zoom.png~
$ sudo mv /usr/share/pixmaps/application-x-zoom.png /usr/share/pixmaps/application-x-zoom.png~
$ sudo pacman -U zoom_x86_64.pkg.tar.xz 

I then reinstalled andit seemed to complete:

but when I then launched zoom, I still got a dialog that reads Version: 3.5.374815.0324

So it didn’t actually upgrade….

or the package doesn’t actually consist a newer version….
