What happens to a variable if it isn't marked as sensitive?

What happens to a variable if it isn't marked as sensitive?
 
If you forget to mark a variable as sensitive, where might it be exposed? I understand it might get written to logs, but I can't find where. 
I did a test where I set a variable to "this variable is not sensitive", and wrote it to a word file. 
I then searched the c: drive for "this variable is not sensitive". It found the docx on c: and a link to the file on sharepoint. But I can't find that phrase recorded anywhere else.
 
Is there somewhere else I should be looking or are logs only written on errors or something?

    Hi,
     
    Setting sensitive option to variable can help in following
     
    1. Prevents viewing confidentials values when running the flow from flow designer (during debug/test)
    2. Also If you check in Power Automate cloud portal under desktop flow activity, you will see that instead of variable value- it will set as <Sensitive Value> as shown in example where bot is trying to write some senstive data to .txt file
     
     
    So if you did not mark variables as senstive the opposite of above 2 will happen.
     
    Feel free to add any points if i miss anything here
     

    Thanks & Regards,

    HI
     
    Also in memory is the big one as well. It's not going to write a warning all the time, as its getting smarter, but if its in Memory it is exposed.
