Automatiing Blob Trigger on Logic App with ARM Templates

I have the following (partial) template. The template also creates a storage account with and a blob container.

The question is, how do I obtain the folderId?

I have tried with resourceId of the blob container but either I'm doing something wrong or I'm going down the wrong track as it's not working.

The JTJmZ2kgx2RhdFE= value was added when I manually created the Logic App.

Any ideas?
