Space not assigned to an organization or admin

I've been working in a Confluence space, and was getting ready to link items with Jira in order to track workflows. Upon trying, it told me that an admin would need to assign Jira. This was strange as I should be an admin, due to me creating the space.

I found that organization admins and site admins are different, so I created an organization but have no way of assigning my Confluence page to that organization. I don't want to have to use a new site domain.

When trying to create a support ticket, it gives me an error about not being able to find my cloud URL.

I'm unsure how to move forward from here, so any assistance or guidance would be greatly appreciated!
