Cannot delete a license server

Hi, there,

I created a license server without checking “Create legacy server” for a trail.

But I could not delete it.

I could not find where to delete or release resources.

And I was trying to delete the service instance,

it showed:

The service instance “0011w000024umcvqae-2022-08-04_09-21” has license server(s) installed on it.
Please return the licenses before deleting the service instance.

I don’t how to return the licenses. Please help guide me to return the licenses.

I have found the solution by googleing.

I have deleted the related resources.
