I think we need to bind the token to the path or dynamically generate the path from the token. Currently we use a forked repo for many tests, which is in the @yhaliaw namespace. We cannot assume that our tokens have access to each other's namespaces.

EDIT: This is not necessary, as @yanksyoon reminded me that the fork is created dynamically in the token owner's ns.

In addition, we may want to stop passing tokens via the INTEGRATION_TEST_ARGS secret, as this would mean sharing our tokens with each other, as someone has to fill in this value.
