Put that question in a separate block. Put that block again before End of survey element in the survey flow. Using JS check if text entry field is not empty then replace all with space character and click next button.

Hi Shashi but that will display the question again to the user right? Is there a way that I can call the questionID of the previous question and delete the answer?

https://community.qualtrics.com/XMcommunity/discussion/comment/49104#Comment_49104Yes, but using JS we can even hide that question and auto advance once the space character is added.

Thanks Shashi! All good now :)
