How to scrape jobs from a Workday job board with PHP?

Question

I am trying to fetch jobs from Worday job boards. One example is Proctor and Gamble here: https://pg.wd5.myworkdayjobs.com/en-US/1000

I can visit the site and see the jobs in the browser. When I look at the network tab I see there's a https://pg.wd5.myworkdayjobs.com/wday/cxs/pg/1000/jobs endpoint that returns all the job listings as JSON via a POST request:

I've written some code to mimic this POST request using PHP 8 and Guzzle 7 but every time I send the request I get a timeout. Is there a way to send a request to this endpoint to get the jobs back as JSON?

This is the code I wrote to hit the endpoint that keeps getting timeouts back:

            $headers = [
                'Accept' => 'application/json',
                'Content-Type' => 'application/json',
                'Accept-Encoding' => 'gzip, deflate, br',
                'Accept-Language' => 'en-US',
                'Connection' => 'keep-alive',
                'Content-Length' => 58,
                'Host' => 'pg.wd5.myworkdayjobs.com',
                'Origin' => 'https://pg.wd5.myworkdayjobs.com',
                'Referer' => 'https://pg.wd5.myworkdayjobs.com/en-US/1000',
            ];
            $client     = new \GuzzleHttp\Client([
                'headers' => $headers
            ]);
            $response = $client->post("https://pg.wd5.myworkdayjobs.com/wday/cxs/pg/1000/jobs", [
                'timeout' => 5,
                'form_params' => ["appliedFacets" => [], "limit" => 20, "offset" => 0, "searchText" => ""]
            ]);

Is there a way I can modify this code to get a 200 response back from the URL like my browser does?
