Call a SharePoint 2013 Site Workflow from Power Automate

Hello!

Trying to build a HTTP Request in Power Automate to trigger a SharePoint 2013 Site Workflow (not list).

I can retrieve the SubscriptionId easily with a POST:

_api/SP.WorkflowServices.WorkflowSubscriptionService.Current/EnumerateSubscriptions()

And my goal is calling a workflow with a specific SubscriptionId to run on an specific ProjectId.

Any hints?

Thanks in advance!
