Sometimes an element on the page subscribes to custom events. You can dispatch events using plain HTML method "el.dispatchEvent" or by using Cypress command "cy.trigger"
cy.get('#signal').then(function ($el) {
$el[0].dispatchEvent(new CustomEvent('go'))
})
// using cy.trigger
cy.get('#signal').trigger('warn')
