Steps to reproduce the problem:
Currently on Chrome Desktop & Android there is a maximum number of 2 notification action buttons.

What is the expected behavior?
On Android, there could be a third notification action button in lieu of the 'Parameter' one.

With a third notification action button, it'd be possible to smartly extend the interactions by extending the number of 'leaves' on a "buttons browsing-tree".

What went wrong?
On Android, the 'Parameter' button displayed along the side of the 2 notification action buttons is not really necessary in a day-to-day use, it's more of an "admin interface" which is rarely used IMHO. Its space could be better used for a third notification button.

Furthermore, the 'Parameter' button is redundant as it's alternatively accessible by long-pressing the notification, which reveals three buttons including the 'Parameter' one - although it requires some guess from the user to discover it.
