How do you get the value of a key in a big map using tezos-client? I don’t get the parameter « identifier of big_map » of « get element of big map , or how to find this identifier. The « get big map value for» is simpler to understand but deprecated.
And how do you discover the indexes of the big maps of a contract? It seems you would have to inspect the storage, and correlate with the type of the storage, and pick out the numbers that correspond to big_maps.
