I would like to add a button that triggers some custom JS code to the top roolbar (not the block level editor toolbar):
Is there an official way to do this? I couldn’t find any documentation about extending the top toolbar.
Thanks
Aaron

This is presently not offered as an extension point. The source for the post editor’s toolbar shows that these items are hard-coded, and do not offer any filters or Slotfills.
Issue #16174 provides a feature request for such extension points.
