Question How to make an in-app update?

Hi, I was working in this for a week and I'm not having good results.
I have an app based on android in Quest 2, and I want to check updates when it start run and if there is some update, download it and do it.
I has been trying with asset bundles and addressables for a while to just think it's impossible or that I'm just doing it wrong.
If it can be done how can I do?
I want to update the app in quest 2 while the updates are stores in gitlab repository or similar.

 

also I don't know if it could be done with unity patch and if it's possible how?

I was seeking for tutorials or information about this and all I could find was about PC or GooglePlay updates
