Can't Override Default google_tag_manager Event

[lsdmi]

Here's my code t.google_tag_manager :push, { event: 'event', action: 'action', category: 'category', label: 'label' }.

Seems it's sending all variables except event to the google tag manager console.
Event variable always says gtm.load, even though I'm passing custom one above.

Works fine if I pass it through dataLayer in js tho. Is there anyone else facing this issue?

Appreciate any help :)
