WP Bottom Menu onclick event

Hi there,
I’m using the WP Bottom Menu plugin which has an option to add an onclick event for custom menu items.

I can’t for the life of me work out what the onclick code should be to get the Side Cart to toggle.

I managed to get the fly cart I’ use’m currently using to trigger with ‘woofc_toggle_cart();’ but using a similar format for the Side Cart doesn’t seem to work.

Here’s a screenshot of the settings page, so you can see what I mean:

Any help you can offer would be very much appreciated!
