Unable to see traces at Application Insights logs using managed identity mode from my deployed app at azure app service

Question

Please Help!!

I want to send my python application logs hosted at azure app service to azure application insights using managed identity based access control. As documented, I have enable system identity for app service and then gave monitoring publisher metrics and component contributor, Log Analytics Contributor access to app service using IAM access control at application insights. However I am not able to see any logs at application insights logs/traces and getting Forbidden error:403. Checked for connection string, access. Any help is welcome. Thanks
