title: Give user permession with Azure AD
body: <p>I have an already deployed application on azure app service which uses azure AD for authentication and authorization.</p>
  <p>Unfortunately the developer who worked on it is no longer available</p>
  <ul>
  <li>i got access to all Azure resources and source code but i cant figure out how can i add my azure account as one of the users to the app (i can login but its an empty view for me unlike what it used to be with the developer access).</li>
  </ul>
  <p>Also i find the app registered on Azure AD and i am an owner there but still with no right access.</p>
  <p>When i try to login localy from the frontend it say</p>
  <pre><code>Selected user account does not exist in tenant 'Default Directory' and 
  cannot access the application '[some numbers] in that tenant. The 
   account needs to be added as an external user in the tenant first. Please use a 
   different account.
  </code></pre>
  <p>Would appreciate any help and many thanks in advance.</p>
