Hi @Peera! Happy to help!
Generally, you can input your locations into the Mapbox component via the Points section & the coordinates section. You can wrap your location data in double curly brackets {{}} if it is going to be a dynamic value from a query or component:
We also have a community post with a more advanced implementation of the Mapbox if you want to check it out: http://community.retool.com/t/geo-series-part-1-google-maps-driving-directions-mapbox/6405
If you get blocked anywhere with this component, can you share some screenshots? Happy to take a look!
