[firebase_dynamic_link] Dynamic link android setup

[mkm279]

I have set up the Firebase Dynamic Link in my app and it is working fine. Users click on the link and are taken to page.link URL and redirected to the app/play store from there. Sometimes there is a bottom sheet which asks to select app/chrome before opening the URL. There is one thing which I am still not clear about though.
I am using the default *.page.link domain for the dynamic link while my deep link domain is wondermart[.]com. And this is my AndroidManifest.xml file:

As you can see I have not made any entry for *.page.link domain. But in a lot of sample repo, I see people making an entry for that instead of their actual deeplink domain. Can someone please clarify what is the right approach here? If I make an entry for *.page.link, the dynamic link starts behaving as deep link and the system tries to open my app with the random path of the dynamic link URL.
