I saw your response that the steps mentioned in the video don't work. Therefore, please directly contact the Eikon support team via MyRefinitiv for any further assistance.
You may need to activate the Excel Add-in. Please refer to this video.
On the Excel Options -> Add-ins window, Thomson Reuters Eikon - Microsoft Office is COM Add-in. You need to go to Manage: Com Add-ins to activate it.
