"Show Page Map" fo results in "Could not find any SAP Fiori projects in workspace"

Hallo BAS Team,

can you please help me and the CAP Team to update cloud-cap-samples so that this problem is solved:

I've cloned the sample project to my BAS Trial instance and I try to open the Page Map via the context menu:

This results in the following warning:

What are the pre-requisites to get the page map displayed? Please send a PR to correct this in the sample repository or help here so that I can create such a pull request.

Best regards
Gregor
