They said we can set configuration like: { "provider": "s3", "name": "My Self-Hosted Storage", "awsAccessKeyId": "your-access-key", "awsSecretAccessKey": "your-secret-key", "region": "us-east-1", "s3BucketName": "your-recordings-bucket", "s3PathPrefix": "recordings/" } But I am trying to figure out where we can set the URL?
