title: "SharePointFullPage" app can't be removed
body: <p>I made a SPFx web part using supportedHosts &quot;SharePointFullPage&quot;
  After a while I removed it from the tenant and the site because I made a totaly new one with new identity.</p>
  <p>Now it is showing in the choices of apps on new page and there is no why to remove it.
  The &quot;Delete from site&quot; does nothing.
  PowerShell <code>Get-PnPApp</code> does not show it either</p>
  <p>Any idea how to get rid of it?
  Thank you

  The green box is the current valid solution.
  the red is the one I can't get rid of. It is not listed in the site or the tenant.</p>
