Using IAM roles instead of Users credentials for Serverless framework

Hi Guys,
Please forgive me for asking the same question if it had been asked again.

I am trying to build a pipeline for server-less deployment using server-less framework as the core along with Jenkins and Bitbucket for the orchestration process.

In our organization we use IAM-Roles instead of Users with access key and credentials and i was trying to find how to use that instead of using users with credentials for the server-less framework.
Also we have multiple accounts and we want to be able to do cross account deployment.

Any advice on how to tackle this problem would be highly appreciated.
Thanks
Abhishek

@wizabhishek IAM roles are given to users so you can just create a IAM user, grant him the role you want and use its credentials.
