Hi @Bamfo Kwakye Ampofo,
The Learning Module you shared is related to Power BI Desktop instead of Excel app.
Copilot in Excel looks like following image. If you still cannot find it in Excel, please refer to: How to find and enable missing Copilot button in Microsoft 365 apps
If you have any issues on Power BI Desktop, it's recommended to post a new thread on: https://community.fabric.microsoft.com/t5/Desktop/bd-p/power-bi-designer
The reason why we recommend posting appropriately is you will get the most qualified pool of respondents, and other partners who read the forums regularly can either share their knowledge or learn from your interaction with us. Thank you for your understanding.
