title: ngx-contextmenu - this.overlay.position(...) connectedTo is not a function
body: <p>I am using <strong>ngx-contextmenu 5.4.0</strong> and recently upgraded <strong>angular version to 13</strong>.</p>
  <p>After upgrade context menu was not visible and was throwing following error.</p>
  <p><a href="https://i.stack.imgur.com/kuVT1.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/kuVT1.png" alt="Overlay error" /></a></p>
  <p>I tried changing version of <strong>@angular/cdk to 11.2.13</strong> and <strong>it worked</strong>.</p>
  <p>But I have some other features which requires @angular/cdk 13.1.1.
  I even tried another combination @angular/cdk 13.1.1 and ngx-contextmenu 6.0.0,
  but even that didn't work.</p>
  <p>How do I go about?</p>
