Cache doesn't appear to work

[jordyvandomselaar]

I call an API endpoint like this:

const { data, error } = useSWR(`${api_endpoint}/invitations/${employee.id}/is-worker-known-in-pms`);

As far as I understood SWR, it would cache the response and re-use it for any additional calls to the same endpoint as long as I don't call mutate() or the user minimizes the browser.

However, I render this component multiple times and I still see multiple calls going to the API. Am I misunderstanding this or am I missing someting?
