stream Function logs to terminal during `sandbox`

Description

It would be helpful to debug Function executions by streaming logs to the terminal where Sandbox is running. For example, viewing a logs for Cognito triggers during an auth flow:

[sandbox] watching for file changes...
[auth:preSignUp] EVENT {...}
[auth:preSignUp] validating email domain
[auth:preSignUp] successfully validated email domain
[auth:postConfirmation] adding user xxxx to group "EVERYONE"
[auth:postConfirmation] creating UserProfile for user xxx
[auth:postConfirmation] failed to create UserProfile for user xxx
# ...Function stack trace

Is there currently any place the view the logs? I am not able to find on docs.

Edit: all logs available on cloudwatch. But would definitely love logs streamed to terminal!

Looks like this may have been resolved. There is an option when starting sandbox for --stream-function-logs per docs.

Just found the backend pr and the docs pr. Both merged in over the last week or so.

Hey folks, as @bradyrichmond mentioned this is now resolved! Be sure to check out the docs at https://docs.amplify.aws/react/build-a-backend/functions/streaming-logs/
