signal-desktop not available in official repos

It seems there isn’t Signal-desktop for Leap 15.3 https://software.opensuse.org/package/signal-desktop
Is it safe to install Signal version for Leap 15.2?

Hi
Grab it from the network:im:signal development repository for Leap 153.;

https://download.opensuse.org/repositories/network:/im:/signal/openSUSE_Leap_15.3/x86_64/

Its here for Leap 15.3:
https://download.opensuse.org/repositories/network:/im:/signal/openSUSE_Leap_15.3/

Is it safe?
I do not know…
It’s on you…

Edit:
second…

Downloaded signal-desktop-5.8.0-lp153.3.1.x86_64.rpm (56.1 MiB). Installing using YaST generate an error message because “/usr/bin/node15” is needed.
Installing nodejs don’t solve the problem.

Add the Repo and install it once more.
In the Repo is another nodejs avaible…

Done. Signal is installed and working. Thanks.
