webform submission Path

I have a webform on the site. I want to get all the entries of the webform but it is not working.
i used the path: /webform_rest/{webform_id}/submission/{uuid}: and can only get a response when the UUID is for a specific entry. when i try to call for the list of off submissions i get an error that the UUID is incorrect.

const username = ""; const password = "!"; const encodedCredentials = btoa(`${username}:${password}`); fetch ('(site URL)/webform_rest/sign_up_for_our_newsletter/submission/bcdfb53b-9bc0-43db-9dfe-c81d005b7058', { headers: { "Authorization": `Basic ${encodedCredentials}` } } ) .then(res => res.json()) .then(data => console.log(data));
