For the creation of a custom track, we need admin permission of your Enterprise plan organization. First, you have to go to the group hub and find the Custom Track section in the left-hand navigation.
Here you have to write a title and description which is a must for everyone.
After that color must be selectable, and then you have to choose the icon also, these all four things are a must. And you must add a minimum of two courses in your custom track.
If all these things are added then Create Custom track button will be clickable otherwise it will be not clickable.
