Can AppImageLauncher be updated on Debian-based distros (Pop!-OS in my case)?

[wherop]

In several places the wiki says that PPAs are a way to keep AppImageLauncher updated:

Note: For Ubuntu 19.04 and newer as well as derivatives, there's two PPAs (personal package archives) available providing a simple way to install and update AppImageLauncher (thanks Peter Jonas for creating and maintaining them):
-- from the README

and also here:

On Ubuntu and derivatives, you can use one of the PPAs provided by Peter Jonas. This way, you receive updates automatically.
-- from the Wiki

Yet, at the same time on Launchpad it says:

Note: PPA packages do not support updating.

When I installed the PPA, the AIL settings app showed that "updater unavailable"

How can I have AIL update when a new version is published, without repeatedly visiting the repository?
