Hi @Dudekula,Amitabh,
The recommended way to interact with a PowerPoint document from an add-in is to use a task pane instead of a dialog box. However, if you still want to use a dialog box, you can use the Office dialog API to open a dialog box from your add-in. The dialog box can be used to collect input from the user, which can then be used to update the content of the PowerPoint document.
To use the Office dialog API in your add-in, you can refer to the following Microsoft documentation: Use the Office dialog API in Office Add-ins.
