I am new to the Figma app and need the hints how to approach the design in the best way. I would like to create the iPhone app mockup, styling it to look like ‘indexed display’. Should I divided the frame for little squares and try to create the fonts based on it or there is easier way to do this ?

So I am designing some wireframes in Figma and I have been tasked with investigating on how we can test our wireframes, is there a way to test wireframes in Figma? Thanks a lot for the responses
