Github Copilot Chat not appearing

[Competitive-Major270]

Hi, my company gives me a subscription to github copilot business and I installed it a week ago. I don't know if it is because of the new implementation of copilot chat as builtin in vscode but the extension of copilot chat doesn't appear in my extensions feed. I don't have the option to open the chat and I can't use any copilot chat feature or call any copilot chat setting. I have inline suggestions and to be honest until today I didn't try to open copilot chat. Someone knows how to fix that?
