This one is really easy. I just needed to dump the output of nc <server address and port> to a text file and try to find picoCTF string in it 🤷♂️
nc <server address and port>
picoCTF
To dump the output and open it in VS Code: nc jupiter.challenges.picoctf.org 4427 > f.txt && code f.txt
nc jupiter.challenges.picoctf.org 4427 > f.txt && code f.txt
picoCTF{digital_plumb3r_5ea1fbd7}
