Herelink capable of caching maps?

Seems I am unable to figure out how to cache maps on the herelink so when we are onsite we can have maps on the controller while not internet connected?

Are you using Solex or QGC?

For QGC, check their instruction:

For Solex, it uses MapBox, which means it loads maps when there is internet. Pre-loaded area will be available when offline.
