How to assign the template when I call the create incident API ?

Hi team,
I know you have create template API, but after I created it and then how to use this template through API call ?
Because there has no template _id field exists in the Create Incident api request.
So how to implement auto bind template when I call the Create Incident API ?

I found the Render Template API, but it requires me to pass the incident_id , it looks a little weird.

thank you !
