Interactive name placeholder

Hi, i’m doing right now a fairly big project as a part of my diploma. The project is to make an absolute interactive story-telling website.

One of the features that I would like to have in the prototype is an interactive name placeholder. What I mean is that at the beggining of the story, the user will write his name down once the website will ask to, and after that, in the next frames and user-flows, the prototype will use the name that the user wrote to create a connection feeling.

Is that in any kind of way even possible in Figma?
