L7 Http instead of cURL

Good day everyone,

I wanted to know if one can convert the below to a Http::get.... function instead of using cURL. I am using the waveapp package, but was wondering how this would be done

curl -X POST "https://gql.waveapps.com/graphql/public" \
  -H "Authorization: Bearer <ACCESS_TOKEN>" \
  -H "Content-Type: application/json" \
  -d '{ "query": "query { user { id defaultEmail } }", "variables": {} }'

$response = Http::withToken('token here')->get('https://gql.waveapps.com/graphql/public', [
	'query' => ['user' => ['id', 'defaultEmail']];
])
