Architects in Germany

Hi

I wanted to ask if it's necessary to register in the chamber of Architects in Germany if anyone wants to practice as an architect in Germany.

Also, does the masters course "Integrative Technologies and Architectural Design Research" from ITECH in University of Stuttgart let you register as an architect? I tried asking the university but they didn't have any clear idea.

I'm and international student exploring the options for MSc. In Architecture, if it helps.

Thanks for the help and advice.
