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

I am having an issue with ghosting.
Using the debug command, ‘Ghost’, it SHOULD allow me to FLY anywhere, through walls, etc.
What actually happens is that the player cannot VOLUNTARILY go up or down, you can ghost, but you slowly drift downwards while moving (Watch the following video for a demonstration of what happens): - YouTube

Any help guys?

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).
