GraphQL Mutation results updating

I have a mutation for my react component which pulls down data:



mutation FetchQuestion($level: Int!, $topic: Topics!)
generateQuestion(level: $level, topic: $topic)
id
question
working
expanded @client
marks




The expanded field is added using a resolver



const GeneratedQuestion = 
expanded: () => false,



The data is passed down to a component to query and render the results



<Mutation mutation=QUESTION_MUTATION variables= level, topic >
(generateQuestion, data ) => <List generateQuestion=generateQuestion data=data />
</Mutation>


However, I then use another mutation to change the value of expanded



const expandQuestion = (_: any, variables: questionID: string , 
cache : any) =>
const id = `GeneratedQuestion:$variables.questionID`
const fragment = gql`
fragment completeQuestion on GeneratedQuestion
expanded

`;
const questions = cache.readFragment( fragment, id );
const data = ...questions, expanded: true ;
cache.writeData( id, data );
return null
;


I would like the List to be updated from the Mutation is has originally, however, I don't believe Mutations work like that.



Instead, I've tried to build a Query directly to that cached but cannot get anything to work as it does not exist directly in my Query Schema. Is there a way for the Mutation to update it's data when the cache is updated? Is there a way to query the cache using <Query />?
