Enable appending extra parameters to a deep link query string

[andreban]

Developers frequently use an extra query parameter like &twa=1 to segment web traffic coming from the Trusted Web Activity implementation. LauncherActivity handles deep links correctly, but doesn't allow configuring appending the extra parameter without developers creating their own LauncherActivity.

Ideally, we would allow developers to configure extra parameters via the AndroidManifest. This would allow developers to add extra parameters without having to write Java code and allow llama-pack to help developers to configure it.

Hi @andreban

How can I create or extend the LauncherActivity? I need to propagate my google ads campaign to my application context. Can you give me an example how to implement that?

Thanks!
