How to pass base version of aws cdk app to multiple teams?

Question

I have prepared a base version of my AWS CDK app. I want to pass it to multiple teams. This teams will perform some additional operations on my base version and publish it on their environments.

For example: my Base Version is: AWS-PipelineStack-V1 It contains multiple stacks created as part of the app creation.

I want to pass AWS-PipelineStack-V1 to Operations & Management Teams. This teams will add/modify few functionalities according to their requirements within the stacks in the cdk app.

How can I share my base version will multiple teams, also giving them an option to add few things to base version.
