How do I let the character fly up and down using the debug command, ghost?

I was looking all over the place as well even asked Gemini and ChatGPT in hopes it was crawled anywhere before. The only answer I got was ThumbMouseButton2 since I use a Logitech G600 I don’t have a third button but rather 12 more…

For anyone searching in the future:
For me it was tapping the scroll wheel left (down) or right (up).
