Allow form submitters to only view their requests within a space

Hi! I need help achieving the following workflow:

I need for users to submit a request form and for them to be able to:
1) access that request without being able to change the status 2)with them only having access to edit specific custom fields

I need for all requests to be stored in a single space/project/folder, but for the submitter to only be able to view requests they've submitted.

I can achieve the ability to restrict them from editing the task via access roles, but because access roles are space-specific, I have to add them to the space, thus giving them access to view all requests in that space.

Can you please advise?
