Support to track custom events

[dana-c0914]

Matomo has support to create triggers of 'Custom event' type, which would work as the following:

Triggered when a custom event is pushed to the Data-Layer. Allows developers to define manually when this trigger should be triggered by pushing an event to the Data-Layer. This way you can for example execute certain actions when a product is added to the cart, or when a user logs in.

One can normally do this by accessing the mtm object attached to the window and push an event:
window['_mtm'].push({ event: 'myCustomEvent' });

What I am wondering is if there is any way to do this via the library, to avoid working with the low level objects.

Thanks in advance for any information.
