I used it in Address worker - so if you'd like to do the same - don't forget to add to to the router

curl http://localhost:10102/trpc/testSessionKey -H 'rollup-address-urn: %SC WALLET ADDRESS URN%' \ -H 'content-type: application/json' \ -X POST \ -d '{"sessionKey": "%SESSION KEY FROM GALAXY%", "publicSessionKey": "%DEV'S PUBLIC KEY%"}'
