I imported the 3 electrum public keys into seahorse ("Passwords and Keys") on Linux mint v22 and copied the electrum .exe file and .asc file to the desktop.

I can't get the .asc to verify with the.exe file.  On windows it was simple as you just click the .asc file and Kleopatra would check whether the public key matched.  However I want to migrate to Linux.  How to do this on Linux mint with a GUI.  I can right click the files but no option to verify the imported public key to the files?
