I hope it doesn't seem like a pointless question and I'm sorry if I don't give all the details first, but I would like to know if I can call from another file enterUsername(userone), where userone would like to be an object with more many features

enterUsername(userone){
       userone=( 
            cy.get('input[name="Parameter.UserName"]').type('userone'),
            cy.get('input[name="Parameter.Password"]').type('useronepass') 
               )
        return this;
    }

From another file calling directly enterUsername(userone) and not enterUsername('userone')

Please note that I have asked something similar and I have been given solutions that I have applied, but only with a call between apostrophes.
