Nextcloud-desktop debian package not available on RaspiOS ARM

On RaspiOS (basically Debian) for x86 I just installed nextcloud-desktop and voila I had a UI client that works.

The nextcloud-desktop package, alas, is not available on RaspiOS for arm, which is a pity, as I use the raspberry pi with RespiOS Desktop via VNC.

Is there a way to get his package also for arm?
