Is there a way to create bulk users which are agents and/or customers?

We are looking to use UVDesk for training IT helpdesk agents.

It was the Redis issue - disabled the Redis extension and resolved the problem.

I have been trying to install UVDesk on shared hosting, where I have full control of the server via Plesk.

Everything is configured, and the server only provides access to MariaDB.

Server: 127.0.0.1
Port: 3306
Username: abcdefg (fake)
Password: abcdefg (fake)
Database: abcdefg

The response is: Details are incorrect! Connection not established.

I do not tick create a database as that has already been completed.

Any reasons why, and if I set the values in .env, is there a way that UVDesk will bypass the database config.
