/join/access-denied throws error on line 19

[brettski]

Describe the bug
When /join/access-denied is called on a session which cannot be joined the page error's on line 19 (

that.us/src/routes/join/access-denied/+page.svelte

Line 19 in 9c56986

if (page.query.has('id')) {

).

The reason for this is page.query is no longer available in newer version of Sveltekit and the value should be checked against something like $page.url.searcParams.

Navigate to the following page to see error
/join/access-denied/?id=UORrxpkPjy5Bv803QA5K
