Just curious, is there a simple way to insert X character at every Y positions of the string? Currently doing it by mapIndexed and joinToString, but looking into more accurate solution. Thought about chunked and joining, but I don't want to have X at the end of the String. Example string is 123456 to become 123456

[hho]

"123456".chunked(2).joinToString(":")?
