theme conflict

Hello support team,

First of all thanks a lot for this amazing plugin.

but I faced the following error that prevents me to use the plugin:

Uncaught TypeError: this.$element.one(…).emulateTransitionEnd is not a function
at Drawer.show (drawer.js?ver=1.2:97:18)

at v.handle (jquery.min.js?ver=3.6.0:2:41048)`

I can see the Drawer Sliding Label in the page, but when I click nothing happen(the Drawer is not opening)
