Hello community,
I'm somewhat of familiar with Fiori elements but this is the first time, I need to extend a given app, in this case, Manage Material coverage (F0251).
My task is to add an additional navigation target to one MRP element. So if MRP element is a production order (FE-AUF), I want to add navigation to shift node transaction (SHN3 or SHN4). At Fiori Elements, it was an easy task to just define another action to SAP standard semantic object. But this will not work here, otherwise I should already see many more navigation targets.

So could someone please give me some hints in how to enhance this app to add a new target? I've read through the extensibility documentation of this app but it seems to me that it only covers how to add additional columns.
