Get error trying to create SQL Server Agent Job with XMLA command

I am trying to run an XMLA command that kicks off an Xevent trace as a SQL Agent Job. (below)

The command works fine in SSMS as an XMLA query.

When I try to save this step as an SSAS Command in an agent job, it throws an exception -

An exception occurred while executing a Transact-SQL statement or batch.
(Microsoft.SQLServer.Connectioninfo)

The @flags parameter is not valid for a job step of type 'ANALYSISCOMMAND'. (Microsoft SQL Server,Error: 14545)

This job step can be saved as TSQL but it will return a syntax error - as it should - when I invoke it.

I have no experience creating agent jobs using xmla code.

The latest SSMS with SQL Server agent on SQL 2019 CU 16 successfully created the job for me. The @flags parameter is on sp_add_jobstep, so compare to what your SSMS is generating.

Here's the job creation script (with the path modified):
