SharePoint Online Custom Webparts

Hi All,

I'm looking for a way to export a Custom Web Part in SharePoint Online.

A old IT employee created a SharePoint Communication site with a lot of Custom Web Parts. This employee doesn't work for the company anymore and i got the task to make some changes to the SharePoint Site/create a new site.

So i hope there is a way to export the custom webparts.

Does anyone know?

Thanks in advance

Chris
