Hide the chat when the side cart is open!

Hello, I would like help solving a problem on my site, recently on my site I installed the helcrunch chat and I would like to know if it is possible to hide the chat when (cart-widget-side) opens and on the product page. I’ve been talking to the helpcrunch team and they gave me these codes that allow me to hide the chat.

Code:
You can hide the widget by calling hideChatWidget method:

HelpCrunch(‘hideChatWidget’);

Force open/close chat after custom event
If you want to open or hide HelpCrunch chat by some custom event on your page – just call openChat / closeChat methods when your event fires:

HelpCrunch(‘openChat’);
HelpCrunch(‘closeChat’);

I would like help to know where to put it.
Attached are some images showing the problem.

Best regards:
