Installing WP Smush Pro and dashboard with composer, automate login at dashboard

Hi There,

We had conversation over chat before, we're trying to use WP Smush Pro installation from composer. That's all OK right now, got it all working fine.

The only thing is that we have the whole process of installing plugins automated. Except one issue with the login from the WPmudev dashboard.
Before WP Smush Pro can work, we have to manually sign in at each site. So we're wondering if it would be possible to automate this, as it is an composer installation. From composer it is already authorised with an API key, so no need to authenticate again?

Thanks in advance!
