How to create a termbase on groupshare cloud

Hi

Could someone help me to find how to create a BT on Groupshare cloud version.

The project is already created and I wanted to know if I have to create the BT first locally on SDL Studio or on groupshare cloud? I could not find where to create on grousphare cloud the same way I did for the TM

Anyone could help me on this?

Kind regards

Laetitia
