How to add javascript to sharepoint online Modern Page
thanhtien19 Microsoft have purposefully locked down modern SharePoint sites to prevent a lot of the customisation that was previously available in older versions. However you can create web parts with the SharePoint Framework SPFx or download samples from github at https://github.com/pnp/sp-dev-fx-webparts/tree/main/samples where there are instructions for downloading and installing them. Also, there is a modern script editor web part available from Add an app in the SharePoint menu.

Are you trying to use the SPFx web part solution for only one "site"?
If yes, you can use the site collection app catalog instead of tenant app catalog.
Check this Microsoft official documentation to enable and use site collection app catalog in SharePoint: Use the SharePoint site collection app catalog
