Astar's zKatana not supported on rpc.walletconnect.com/v1/

[maxisch]

I was checking https://quickswap.exchange/

and if you inspect the console when using zKatana you get: {"status":"FAILED","reasons":[{"field":"chainId","description":"We don't support the chainId you provided: eip155:1261120"}]}

curl example:

curl 'https://rpc.walletconnect.com/v1/?chainId=eip155:1261120&projectId=4b8065e47a7572a1b65838e57557f93d' \
