How to update MAUI android app by itself without google play

Question

I have an android app which has been created using MAUI with .Net v8.

My requirement is to update the android app when click on a button and the app should download the app from a shared location in cloud and then install the new update.

In future I suppose to do it in the background.

I found few articles which give some idea.

But, I didn't get enough information from them to achieve it using MAUI.

So, I expect a proper resource to follow to achieve my requirement.

Articles I found..
