Installing referrals bundle mautic 4.3.1

Your software
My Mautic version is: 4.3.1
My PHP version is: 7.4.3
My Database type and version is: Mariadb 10.3

Your problem
My problem is: Doing a fresh mautic composer install on new server. Everything works fine.
However, I can’t install the referral plugin (GitHub - maatoo-io/MauticReferralsBundle).
Composer install doesn’t work. Extracting the zip in the plugin folder is no problem, but doesn’t show up in the plugin list.

Is the bundle Mautic 4.3 compliant? Are there alternatives if not? The referral bundle is a must have for my mautic install.

Kind regards,
