I have installed pega platform and CRM application and also configured pega chat on a different computer with different database, redis and node. Now trying to configure the pega chat with pega platform. I was able to configure it but getting error when trying to invoke chat option from CRM application " You don't have a chat account on this host"

Can anyone tell me what is needed? I don't have design studio. But dev studio and admin studio are working in pega platform
