I am trying to develop an extension that runs on a Windows machine and supports a commercial Office 2019 Excel. Excel uses IE11 perpetual browser for this. When trying to load the name using
workbook.load("name"); await context.sync();
It gives "The API you are trying to use could not be found. It may be available in a newer version of Excel" . On doing a console.log(), I get against that property.
Can anybody help on what is the recommended way to fetch workbook name in Excel add-in?
