How to Add External Map in basemap Gallary

Hi CesiumJs Community, I am developing a 3d viewer project using cesiumjs. I have to use Hong Kong government Map services (2D Map) as basemap(an option in cesium basemap gallary). I don’t know how to add it in basemap gallery. I need help, please let me know how can I achieve it.

Hi @Jacky, Thank you for your reply and reference. But I don’t think I am looking for this whatever link you have shared. Actually, I want to add a 2D Map (It could be topographic, openstreet, or any other map) in default basemap gallery. Also, I want both functionalities (2D & 3D) as per basemap selection.
