Answer: Serverless RDS Instances do not support public access.

During configuration you won't be able to see this toggle, and your instance, while running, will not be visible from the public internet:

Since as @fastmultiplication said, you can't access serverless RDS from the public internet, you will need to connect using an SSH tunnel. You can also set it up using MySQL Workbench.
