JSON Unmarshelling typed.TypedData

[saguillo2000]

I am currently working with AVNU API and there is a method that provides a TypedData JSON, as follows:

{"types":{"StarknetDomain":[{"name":"name","type":"shortstring"},{"name":"version","type":"shortstring"},{"name":"chainId","type":"shortstring"},{"name":"revision","type":"shortstring"}],"OutsideExecution":[{"name":"Caller","type":"ContractAddress"},{"name":"Nonce","type":"felt"},{"name":"Execute After","type":"u128"},{"name":"Execute Before","type":"u128"},{"name":"Calls","type":"Call*"}],"Call":[{"name":"To","type":"ContractAddress"},{"name":"Selector","type":"selector"},{"name":"Calldata","type":"felt*"}]},"primaryType":"OutsideExecution","domain":{"name":"Account.execute......

And I perform the classic method for umarshelling in Go as follows:

var buildResponse typed.TypedData
err = json.Unmarshal(body, &buildResponse)
if err != nil {
log.Fatalf("Failed to unmarshal the response body: %v", err)
return typed.TypedData{}, err
}

Seems like there is no JSON like this for unmarshelling:

type GasTokenPrice struct {
TokenAddress string json:"tokenAddress"
GasFeesInGasToken string json:"gasFeesInGasToken"
GasFeesInUsd float64 json:"gasFeesInUsd"
}

Is there another way to perform this unmarshal?
