bq. Isn't that also true for Approach 1, just that we'd have to put the tokens into a store
owned by the collector instead of the RM?
No. We do not have state store for managed apps in approach 1. Tokens are regenerated upon
restart and passed onto AM along with collector address(which also changes upon restart).
