There is an example in Google Cloud SQL provider that uses

std.TrimSuffix

:

invokeTrimsuffix, err := std.Trimsuffix(ctx, &std.TrimsuffixArgs{
			Input:  serviceAccount.Email,
			Suffix: ".<http://gserviceaccount.com|gserviceaccount.com>",
		}, nil)
		if err != nil {
			return err
		}

However

TrimSuffixArgs.Input

is declared as

string

, not as

pulumi.StringInput

. Whats' the right way to invoke

std.Trimsuffix

on an output?
