To do this you need to Copy-Paste the source code of the bot to a new, unsaved, bot.
To copy the source of your bot via Bot Settings > Bot source (with developer mode enabled) and paste this tp the Source of the new, unsaved, bot.
Important note: you can only paste this before you save the bot for the first time after you have chosen your template, otherwise it will not work.
And save your bot! You have now copied your bot.
