Migrate our flow to PowerBI API

We currently have a PBI Desktop report that we update with power automate on a remote machine. We would like to migrate this workflow to PBI Service and supply the data through the API, then get the reports back.
I can provide the input data file and the report. All the calculations and templating are already done.
We just need help for the PBI Service API aspect.

Please do not answer if you have never used PBI API.
