Assistance Required for Running Office Add-ins in Embedded Excel

Question

Description:

I have developed an Office JavaScript add-in hosted in Azure, which works seamlessly with Excel files stored in SharePoint. Currently, I have a web application where I need to embed an Excel file and utilize this add-in directly within the embedded form of Office 365 Excel.

Issue:

I am facing difficulties in running the add-in directly in the embedded version of Office 365 Excel. I need guidance on how to achieve this functionality.

Request:

Could you please provide any sample code or documentation that can help me run the Office add-in in the embedded form of Excel? Any insights or solutions to this issue would be greatly appreciated.
