Way-finding project unity & c#

Hope all is well, I am trying to execute a basic wayfinding project with Unity and C#, however, I am having difficulties.

So the basic idea is that there will be a list of locations and with on click of the UI button (destination 1/ destination 2), the "player" would then travel to whatever destination had been clicked showing its path of travel, then resetting back to the rest UI after a certain amount of seconds.

However, I am having difficulties understanding how to use the Button to make this happen as well as how to store the location information (list, array etc?) and if the rest UI would need to be a separate scene in unity as a kind of "start menu" or it can all be done within a single scene.

I have some code put together that takes a single player to a single location however would you be able to help implement multiple locations?

Look forward to hearing from you.

Kind regards,

Alex
