How can I build a gasless txn experience using the relayer?

[0xbsa]

I have seen the relayer docs here: https://docs.sequence.xyz/relayer/building-relaying-server

I'm trying to integrate the relayer with my Go backend but there seems to be some differences in TS implementation (sequence.js) and this project. The relayer service bindings are not exactly the same. The TS bindings allow passing & fetching quote in sendMetaTxn & feeOptions calls respectively. This capability is missing the Go rpc bindings (or atleast I couldn't figure it out).

Edit: feeOptions method is missing in the Go relayer bindings 😞

Please advise with achieving the same result as the docs with Go client. Thanks

My understanding is that I'll need gas quotes from the relayer in order to craft the gas payment transaction using a (potentially) non-native token for gas. Is this correct?

@pkieltyka would you mind taking a look?
