Required subscription for MT-Add-on Development for Trados Live

Hello,

I want to develop an Add-on for Machine Translation for Trados Live. However, I don't have access to the tab in the RWS AppStore to manage my own Add-ons (which is mentioned in the Extensibility Documentation) (i.e. it is not visible) and therefore I can't register my Add-on.

I suspect that I have the wrong subscription (Freelance). Which subscription do I need as a developer? Or is this problem not related to my subscription?

Thanks for your help!
