-### Connection Issues
-- `aiomysql` uses `PyMySQL` which requires the `mysql_native_password` plugin to be used. Can be checked and changed via:
-```sql
-SELECT user, host, plugin FROM mysql.user WHERE user='backend-push-notifications';
-ALTER USER 'backend-push-notifications'@'%' IDENTIFIED WITH mysql_native_password BY 'db_password';
