Log Stream Not creating when i run lambda

Hello, i created a log group for my lambda using cloud formation, and i when i run my cloudformation scripts, the lambda function includes the cloudwatch log trigger. When i invoke the lambda, the log group i created using the cloudformation doesn’t have any log stream in it, but it seems cloudformation automatically creates a log group for the lambda regardless if i am creating one using cloudformation and including it to the function.

Is there any advice please?
