title: Get buddypress group slug by passing its ID
body: <p>I would like to be able to get a link to a specific buddypress group but by only using the groups ID on a template page.</p>
  
  <p>The admin inputs the groups ID as a custom field on the page, then using this I would like it to be able to generate the groups slug to then create a link to it</p>
  
  <p>Any help is appreciated</p>
