Thank you! 🎖

Good catch!

I thought we decided to just have the union of the values here and not the "Typeof"

[jessiehuff]

I believe that we need the typeof for the older consumers using the enum.

[tlabaj]

I think we should add more verification steps here. We dod not verify that the copy actually works and I think we need to.

[jessiehuff]

Do you know of a good way to test the copy paste feature? I tried this:

it('Verify copy to clipboard works', () => {
    const form = cy.get('.pf-c-form-control');
    form.clear().type('Hi'); 
    cy.get('.pf-c-clipboard-copy__group-copy').click(); 
    cy.get('.pf-c-form-control').clear().type('{cmd}v');
    form.should('have.value', 'Hi'); 
  });

But it always ends up typing "v" instead of doing a paste. I've been looking into it, but I'm not sure what the solution would be: cypress-io/cypress#3316
