Word Online - Angular Add-in Auto-Open Error in Manifest Validation

Question

Good Morning,

I'm developing a Word Online add-in using Angular, and I'd like the add-in to open automatically whenever a Word document is opened—without requiring the user to click a button in the task pane. I've tried updating the manifest file (modifying the section after the <Host> tag and incrementing the version), but I'm now encountering the error: "Your add-in manifest is not valid."

I'm getting those errors when I tried validate the manifest

Error #1:

Package Type Not Identified: We could not recognize any supported add-in type

Error #2:

Wrong Package: Your package does not match submission type.
