How do quill editors add slices?

I use the quill editor
but I don"t know how to add slices.
the current situation is to add slices directly, but it doesn"t work after sending it out
.
how do I deal with the photos on the editor that I can batch upload to the file I specified and then return to the location on the original editor?
this is a little beyond my understanding, so I hope some great gods can give me some advice! Thank you


Custom handler or Custom toolbar, change the picture add button to your own upload logic. Uploading a file will only insert the picture into a rich text editor
