react uselazyquery and usequery

// https://www.apollographql.com/docs/react/data/queries/#executing-queries-manually
When React mounts and renders a component that calls the useQuery hook, 
Apollo Client automatically executes the specified query. But what if 
you want to execute a query in response to a different event, 
such as a user clicking a button? The useLazyQuery hook is perfect 
for executing queries in response to events other than component 
rendering. This hook acts just like useQuery, with one key exception: 
when useLazyQuery is called, it does not immediately execute its 
associated query. Instead, it returns a function in its result 
tuple that you can call whenever you're ready to execute the query.
