Hey, I am trying to create workload identity pool using below code. I am not able to resolve the provider google_beta. Can any help me with this? I tried importing github.com/hashicorp/terraform-provider-google-beta/google-beta but the dependency sync is failing Go version 1.16

pulumi.Run(func(ctx *pulumi.Context) error {
		_, err := iam.NewWorkloadIdentityPool(ctx, "example", &iam.WorkloadIdentityPoolArgs{
			WorkloadIdentityPoolId: pulumi.String("example-pool"),
		}, pulumi.Provider(google_beta))
		if err != nil {
			return err
		}
		return nil
	})

I've opened https://github.com/pulumi/docs/issues/7720 for this issue
