How can i write a comments in excel footer

Hello Excel Expert,
I want to write a comment in excel footer without using header & footer option.
I want to write the comments using code.
My question " HOW CAN I WRITE THE CODE & WHERE I WRITE THE CODE" for Example I want to write "Powered by Tareq" when I print the excel sheet then print the
Powered by Tareq" in the footer.
It is printable but not visible.
Ok, thanks,
Have a good time.
