Probably worth adding a check to see if secrets are going to be available, similar to:

firebase-android-sdk/.github/workflows/ci_tests_experimental.yml

Lines 106 to 107 in 381bf87

	# only run on post submit or PRs not originating from forks.
	if: (github.repository == 'Firebase/firebase-android-sdk' && github.event_name == 'push') || (github.event_name == 'pull_request' && github.event.pull_request.head.repo.full_name == github.repository)

[yifanyang]

Done. The smoke tests were enabled only for presubmit on Prow, therefore it is set to trigger only on pull_request here, hence only github.event.pull_request.head.repo.full_name == github.repository.
