Authorised javascript origin

Hi, we are creating an OAuth consent screen login in terraform, and testing failed because we were meant to configure the authorized javascript origin for this to work but don’t know how to configure this in terraform. We need help/advice. We are using the google_iap_brand and google_iap_client for this task. please refer to the pr link below for this task

Were you able to figure this out? I am looking to accomplish something similar
