AWS: Re-use amazon Cognito Userpool in multiple serverless applications - amazon-web-services

Question

I have divided my serverless project in to multiple projects to avoid template error resource > 200. Now I am facing another error.
I have implemented authentication and authorization using AWS cognito which works well for lambda functions in one serverless application. I am trying to re-use same Cognito Userpool for authorizing API's in another serverless project. However, each serverless project creates UserPool again with same name in Cognito. How to avoid this issue.
Here is the how my serverless.yml and dummy response look like in lambda functions
CognitoUserPool:
Type: "AWS::Cognito::UserPool"

MfaConfiguration: OFF

CognitoUserPoolClient:
