How can i update the Cryptomator appimage version in Linux Kubuntu?

I’m ussing Cryptomator 1.5.11 appimage on Linux Kubuntu 20.04LTS

I downloaded the latest version file “cryptomator-1.5.12-x86_64.AppImage”, make executable by running chmod +x cryptomator-1.5.12-x86_64.AppImage
I deleted the old file “cryptomator-1.5.11-x86_64.AppImage” and now I run the new one but I still get the old version 1.5.11.

how can i update the version? thank you

Sorry for my bad english

solved, I installed from the ppa:
sudo add-apt-repository ppa:sebastian-stenzel/cryptomator
sudo apt-get update
sudo apt-get install cryptomator

thank you
