Does creating a Fabric workspace require Power BI Pro license?

I'm trying to create a Fabric workspace on a Fabric Trial capacity, but getting asked to upgrade to a Power BI Pro license:

My impression was that Power BI Pro license was only required for creating Power BI items (semantic model, report and dataflow gen1).

But I'm unable to create a Fabric workspace without having a Power BI Pro license.
