Trying to set up AWS OIDC Provider programmatically, where can I find the Keycloak thumbprint that I can supply to the aws apis?

We are trying to set up an AWS Iam OIDC identity provider programmatically? In order to do that I need to supply the url to the realm, the audience(the client id), and the thumbprint. I have the first two but don’t have the last, the thumbprint.

How do I either locate or generate that thumbprint so that I can supply it to the AWS api post call?

Thanks for any help!
