Summary

I have a use case where a secondary variant would fit better than a tertiary, and a primary wouldn't be appropriate.

We should take into consideration that a secondary menu like this would be very similar to our Filter trigger.

That makes me question if there should be more difference between the style of the secondary action and a filter.

In addition to that, the next step could be to define when we should apply the secondary menu.
