Passing parameter in a custom command to a fixture

[GioBrella]

Hi! I am trying to use the argument in the custom command for the fixture inside that command, but it is not working that well.

Cypress.Commands.add('checkHeader', (sponsor) => {
cy.fixture('sponsors').then(({ sponsor }) => {
cy.get('.some-class')
.contains(sponsor.name)
.click()
})

So I want to pass the sponsor inside the command and then assert that the element contains name's value from the sponsor fixture. Anyone has an idea how to make this work? Thanks in advance!
