in ArcGIS Pro, is it possible to add a button to an existing tab on the ribbon? I'd like to have my button appear on the Insert tab rather than the default Add-In tab.
I tried to add it to esri_mapping_insertTab, but that doesn't seem to work.
<tabs>
<tab id="esri_mapping_insertTab">
<group refID="My_Group1" />
</tab>
</tabs>
