React application inside Confluence

I’m doing a POC with Atlassian Confluence and Jira and Jira Service Desk tools (docker version) for my customer. I’m using “atlassian/confluence-” and “atlassian/jira-software” founded in docker hub. In this POC i have to migrate into Confluence some web application written with React e/o Angular. In the atlassian community i found only one solution: use the version o f atlassian tool using Atlassian Connect Express. Do you have some suggestion to do this without solution? If it is possible, can you send me how.
