Here is the page that tesla provides as guidance for sharing power from gen 3 wall connectors. Have you checked here?
Wall Connector Power Sharing | Tesla Support
With Power Sharing, you can allow up to six 3 Wall Connectors to share power and charge multiple vehicles at once. Learn how to set up and troubleshoot Power Sharing.
In addition to the above, make sure to check the installation manual.
If you want to run a 100A circuit from your main panel, you should put a sub-panel near the Wall Connectors. You don't have to use the Power Sharing feature if you use 50A breakers in the sub-panel. If you want the maximum 48A charging speed, then you have to use 60A breakers and the appropriate gauge wire.
People think a subpanel is expensive, but the parts are not expensive.
That's only ~$60 for the sub-panel and two 60A breakers. The 100A run from the main needs 3ga copper THHN in conduit and the Wall Connectors need 6ga copper THHN in conduit. If you want to use Romex for the 100A run, you would need 1ga copper or 1/0 Aluminum wire.
