Change password protected text reactions

I’ve been able to change the text on password protected pages by adding a code in the functions file as explained at this url:

At the same page – under the part that I successfully changed – there is also the message that it’s not posibble to see the reactions because it’s a password protected page. I would also like to make some text changes here. Is that possible?
