How do I save characters to a save game so that I can spawn in with the same character that I chose even after leaving the game?

Im just confused on how to save a an actuall character like what would be the variable type in the save game and would I save the game after my set character node? I just never saved an actuall pawn that would posses before. Just mainly on where do I place the things you listed above like in which blueprints. Kind of help me connect what you stated above to what I already have a little more plz.
