Hi Community. Have head scratching question.
I can add SharePoint apps to SharePoint Online site collections using PowerShell CSOM if I have the .app file at hand. (LoadAndInstall method) However, For Nintex Workflows and Forms for Office 365, there is no such .app file that I can access to since app is distributed from Marketplace.
Is there a possibility of adding Nintex WFs and Forms app to site collections programmatically?
