Azure: manually add app service certificate to key vault

Question

Azure has a simple way of adding an App Service Certificate to a Key Vault from the web interface. I did this and later I accidentally deleted the certificate from the Key Vault. The App Service Certificate resource is still there, but the certificate no longer shows up in my Key Vault (obviously).

Is there a way that I can re-add my App Service Certificate to my Key Vault?

... but the cert is no longer available in the Key Vault:

Answer 1

App Service Certificate stores the private certificate into a user-provided Key Vault secret. When App Service Certificate is deployed into a web app, a Web Apps resource provider deploys it from the Key Vault secret that's associated with App Service Certificate.

So, when you add app service certificate to azure keyvault, you could not see anything in Certificate option.
