Multiple IAM users cannot deploy to same stack

I have a dev team that is working on some serverless code using jets and we share the same github repo but when we deploy, we deploy to separate stacks because our IAM user is different.
So for cases where we want to be able to have multiple devs deploy to the same stack for staging or production, how do we achieve this?

Presumably we should be able to set somewhere in development.rb or production.rb a cloudformation ARN or something so that jets knows to deploy to the same stack.

Any comments from the gurus?

:thinking: Should be able to deploy with different IAM users. Main thing that’s needed are http://rubyonjets.com/docs/minimal-deploy-iam/ Unsure on the issue.
