Can we automate flex application using cypress

I am stuck with a flex element. I want to click 'Save' element which is a flex element as can be seen from attached dom. I tried various solutions including one mentioned below by still not working.

 cy.get('div.MuiGrid-root.MuiGrid-item.MuiGrid-grid-xs-12.MuiGrid-grid-sm-12.MuiGrid-grid-md- 
 12.MuiGrid-grid-lg-12')
   .eq(2)
   .within(() => {
     cy.contains('span', 'Save').click()
   })

Thanks in advance for helping me find a solution.
