I'm trying to deploy Word Add-ins on documents via WOPI hosted application using an On Premise Office Online server.
I have enabled addins on my OOS instance using following Powershell command:
Set-OfficeWebAppsFarm - OfficeAddinEnabled:$true
However when I open a document and click on Insert/Office Add-ins, I get the following error: Error: Please add or enable add-in catalogs from the Trust Center
My question is how do I access Trust Center and enable add-in catalogs?
