I am making a click based game. I need to print out a log of the actions(clicks) made by the person and store that log to be used later. How can i do that?

Hello, I am working on a game in which the user will be clicking on different buttons to move(play the game). I need to print out the log of the buttons pressed by the person and store them in a dataframe in unity. For example, if there is a button called "go", coloured green, when the user presses it, the log should generate that > "go" button pressed. I really need your help. Also, how can i access the dataframe after the game ends. I need it to be stored so i can view it after the game. Thank you so much.
