Looks like, it's in the webpack mix of flame.js
'~/app/system/assets/ui/js/flashmessage.js',
328 '~/app/system/assets/ui/js/toggler.js',
329: '~/app/system/assets/ui/js/trigger.js',
330 ], '~/app/system/assets/ui/flame.js', 'admin');
331
However, not being called on the frontend, any clue where is the best practice in which i should be calling trigger.js? And do you think i should call toggler as well?
