Why won't Laravel Sail allow me to connect to the DB - php

Question

Anyone familiar with using Laravel Sail? I can't find for the life of me figure out why I can't connect to myDb using the credentials provided when installing Sail.
My DB credentials in the .env file:
DB_CONNECTION=mysql
DB_HOST=localhost
DB_PORT=3307
DB_DATABASE=myDb
DB_USERNAME=sail
DB_PASSWORD=password
I've tried:
switching DB_HOST back and forth from 127.0.0.1 to localhost
but still getting that same error.
switching DB_HOST to mysql but still getting that same error.
running docker ps -a | grep mysql and the output is: 8b1ef6c28b4e mysql/mysql-server:8.0 "/entrypoint.sh mysq…" 4 minutes ago Up 4 minutes (healthy) 3306/tcp, 33060-33061/tcp, 0.0.0.0:3307->3307/tcp myApp-mysql-1 so no issues with the connection per the output.
running ./vendor/bin/sail sail mysql -u root -p and it allowed me access to mysql on the CLI
almost everything else out there to no avail
Not sure what else to do. How can I connect to my db in a GUI?

Change the DB_HOST variable to mysql as the following:
DB_CONNECTION=mysql
DB_HOST=mysql
DB_PORT=3307
DB_DATABASE=myDb
DB_USERNAME=sail
DB_PASSWORD=password
