Module for Jira Customer Portal

Hello,

I am building a custom app for the customer portal and would like to implement a feature where users can click on a table row to view more detailed information about that certain element. Upon clicking, the user should be navigated to a new page within the customer portal, similar to how a Confluence page displays detailed content.

However, I couldn’t find any specific module in the Atlassian documentation that allows creating custom pages within the customer portal. Is there a module or recommended approach for adding this functionality, or would it require a workaround?
