Regex (JS) — Match any 5-character combination, but ignore 5-character repeat

I struggle with regular expressions, and I've been trying to make one that can match any 5-character combination of X and O, but ignore it if it repeats X or O EXACTLY 5 times.

This is what I came up with:

X{1,4}|O{1,4}
X|O{1,4}

those expressions match (I want it to ignore the XXXXX and OOOOO): enter image description here

I also tried using the non-capturing group (?:), but it didn't work out too well.

You may try the below assertion based regex.

^(?!(?:X{5}|O{5})$)(?=.*X)(?=.*O)[XO]{5}$
