How can I delete a variable amount of text for every row?

Hello, I have scraped a large number of posts and replies from X for my thesis and right now I would like to delete the particular text that is “@[original poster]” that is found in every reply.

The problem is that I’ve scraped the replies from many different posts, so I’m not dealing with the same text:

Is there a way to do this maybe with wildcards, even when there are multiple mentions in the same row? I tried using the String Manipulation (Multi Column) node with wildcards, but I couldn’t make it work.

I would rather not brute force the issue and write a replace() command for every mention I can phisically read.

Thank you in advance!
