"Draft with Copilot" in Sales Hub Email Activity

Hi everyone, could anyone help me out how to add "Draft with Copilot" option in Sales Hub Email. I have enabled the copilot features in the environment and also enabled Contextual email drafting with AI in the application settings. In my personal tenant account that is working fine, but not here. How do I get that Draft with Copilot option / Modern version of drafting emails?
