buttons function

Hello everybody, I gotta say I am impressed with Figma, it is intuitive and easy to work. I am different occupation than web developer, I am just experimenting with page for my work. Simple page with about contacts and couple galleries with pictures. I manage to make everything as I planned but I have question about buttons. On youtube most of them are about design. But how to connect button with something, ? drag and drop same like prototyping slides/frames etc? I have 16 pages with menu bar that is same on every page. Now “About” button do I have to go on every page and assign where “About” button go or there is different approach. I made mistake on beginning and didn’t put Font, background, colors buttons on different asset page and then to bring in main but done all one one page.
Thanks in advance
