Add a specific IAM role to the ECS task definition

Question

I have an ECS task running a container that requires permissions from resources, that are all a part of a specific IAM role. I am trying to add that specific role to the task definition on the console, but the only role I see is the auto-generated one by ECS.

I don't see all the IAM role in the dropdown. How do I access them?
