Welcome to Connect, @Hamishc6
Unfortunately the approval process of roads in Google Maps has been reduced a lot in the last year, especially for cycling / pedestrians path.
However, to provide some better indication, we need to see it. So pleas, as requested also by @doni_hariadi , provide a link in Google Maps with the position of the pathway you want to add.
In addition, as you are writing for help, I want to inform you that I am changing the category and the tags of your post to better reflect your content. For more details please read: What are Connect categories?
