Bought Lost Mines - can I use those tokens in my existing homebrew games?

Just bought Lost Mines of Phandelver, and I am excited to run it.  My question though is can I use the tokens for the monsters in my home brew games?

You can create a new campaign with the Phandelver content and then not use the stuff you don't want (creating custom maps and characters, etc. instead of relying on the built-in ones), even including deleting assets, characters, and handouts from the campaign. If you get a Pro subscription, you can use the Transmogrifier tool to move things from a Phandelver campaign to another campaign you've created.
