Cannot Access Cowork

Hi, I'm based in the UK and have a M365 Copilot (Premium) Licence. I am trying to use Cowork and submitted a request a few weeks ago - it now states 'Request Sent'. I'm a Global Admin and have been all around the various Admin Centers trying to find where I can approve the request/enable Cowork and setup Copilot credits. Just wondering if anyone can point me in the right direction. Thanks.
