Replace Default SharePoint Online New\Edit\Display forms with custom spfx webpart in Modern UI

Hi All,

 I am working in Sharepoint Online 2019. I had a requirement to create custom forms for list.(Display,Edit,New) .I done with SPFx webparts and its working fine in Classic UI but I am unable to do with Modern UI. My Question is how to achieve custom forms using SPFx in Modern UI ( New Experience). Power Apps does not fulfill my requirements.

Note: I am expecting behavior like Plumsail Modern custom form!

Please Help!

Thanks
