Explore Assistant is not visible to User

[vikramjagtap233]

We have acquired a Looker Enterprise license and have set up a chat assistant in Looker.
We are facing below issues

1. Chat Assistant Feature : Only admin users can view the chat assistant feature, while normal users like Developer, User, or Viewer cannot access it.
2. Retry Failure, Negative Prompting, Greetings, and Prompt Training : Our team is struggling with these aspects.

If anyone knows how to enable the chat assistant for these other user roles, please let me know.
