Cannot find the Clan joining button? The clan name doesn't show on your gamertag?

For the name of the clan appears on your gamertag you must not only join the group but also in a further step you must join the clan. Simply go to the top left of the group page where it says the name of the clan, in our case Lone Wolves Summon "More than the sum", and you will see a button next to "Interact" saying "Set as Xbox Clan", click on it and you are set. You will display the name of the clan under your gamertag and make us all proud of your victories :) Note: If you cannot see that button, be aware that you only see the clan joining button on internet, it doesn't show on the bungie app.
