Hi,

I would like to show the namespace workflows based on user role in temporal-web, how can be achieved & is there any pseudo code?

Roles & namespaces

- role1 : role1-ns1
- role2 : role2-ns2

How do you authenticate users? If you use JWT tokens, then you can see to which namespace they should and should not access. [This section](https://docs.temporal.io/docs/server/security/#authorization) of the docs shows how to authorize users on the server.  
Or perhaps you already looked at this and have a different problem?

Have you found [defaultAuthorizer](https://github.com/temporalio/temporal/blob/077d39c775d589427256f5c94e2142e21deb2d81/common/authorization/default_authorizer.go#L47) and [defaultJWTClaimMapper](https://github.com/temporalio/temporal/blob/077d39c775d589427256f5c94e2142e21deb2d81/common/authorization/default_jwt_claim_mapper.go#L66) already?
