We make heavy utilization of Copilot Studio lite and full. Lite has quick access to SharePoint/Teams data. Full has access to _any_ data that has a Power Platform connector, REST API, MCP server, or Copilot [Graph] connector, all of which you can build or buy yourself. SAP, SQL, Databricks, you name it, Copilot Studio full can consume it.

It sounds like you don't have an M365 Copilot license but are instead using Copilot 365 Chat (the naming is horrid, absolutely).
