We have developed an add-in using a C# VSTO add-in project in Visual Studio 2022. However, we now need to implement the same functionality for the web version, New Outlook, and mobile compatibility. Unfortunately, there doesn't seem to be proper documentation available for this transition.

Could you please share your thoughts on how we can convert the VSTO add-in to meet these requirements?
