Switching from openssl-1 to openssl-3?

English Install/Boot/Login

How should I do this. I see that both are installed. But when I ask for version, I get this:

I need to switch to openssl-3 to run an AppImage.

Yes. You can do that at the command line.
But (I suspect) the call within the AppImage is just “openssl”.
I was hopping for a technique like that used with packages like python or java where you can a direct base name (python, java or in my case) openssl to the required version.

To part answer my own question. Following additional research, I think a solution may be:
alternatives and update-alternatives
There is also a management tool in the Yast Control Center. My problem now is how to use the tool to safely switch from the currently defined openssl = openssl-1 to openssl = openssl-3.
Reading the very limited Help, it only covers editing existing entries and not creating new ones.

Can anyone offer any help?
