There should be Add-In webpart(Client webpart) also added to project, here is how-to: https://github.com/SharePoint/sp-dev-docs/blob/master/docs/sp-add-ins/include-an-add-in-part-in-the-provider-hosted-add-in.md
I used these examples and was able to deploy Provider-Hosted App example from PnP
But I don't see my App in "Edit Page" -> "Insert" -> "App Part". How can I insert it in SharePoint page?
SP version: SharePoint Online
