IPv6 Forwarding should be activated by the OTBR-Installation. This is what I got as IP-Addresses:

The route should be there already, otherwise configure it with ip -6 route add ....
You must use the Link-Local-Address LLA of the wpan0 interface as gateway:
Netzwerk: 2000::
Präfix: 64
Gateway: fe80::5c57:74a8:7469:3bf5
