Looking good and is working to do what we want 👍 Left some suggestions and a comment in hopes of polishing things up a bit.

Thanks for adding those changes, this is looking good! I added two minor suggestions, and please merge the master branch once more into your branch so the checks are able to pass.

I was checking the docs about add_filter but couldn't find what is the best practice to write add_filter I mean whether we should write it in the class __construct or any class method and so on.

Hmm not sure I fully understood the question being asked here so feel free to clarify if I missed something. As an end user, I would be able to do something like

function my_jetpack_podcast_helper_tracks_quantity( $tracks_quantity ) {
	return 42;
}
add_filter( 'jetpack_podcast_helper_tracks_quantity', 'my_jetpack_podcast_helper_tracks_quantity' );

My personal preference would be to add that to a mu-plugin file, or perhaps a child theme's functions.php file. Adding that example snippet seems to work well:

PR is up to date 🎉

Oh God! I was writing add_filter statement in the wp core functions.php! So stupid 😞

Thanks once again Samiff & jeherve. Really appreciate your efforts and patience ❤️

Hopefully, I will keep this in mind that there is functions.php file in theme as well. 😥

Thanks for the contribution @amustaque97 these changes are now merged and will be shipped as part of Jetpack version 10.4 on 2021-12-07 🎉
