To allow Custom Headers feature your graphQLFetcher might take an extra argument
and supply it instead of headers:
function graphQLFetcher(graphQLParams, myCustomHeaders) {
return fetch(window.location.origin + '/graphql', {
method: 'post',
headers: myCustomHeaders,
body: JSON.stringify(graphQLParams),
}).then(response => response.json());
