Upload Image through ngx-CkEditor in Angular 7

Question

I am using ngx-ckeditor in my Angular7 project, I need to upload the file, it could be .pdf, .csv, .jgp etc. I have tried few options but i was not able to upload image through Editor. There is no such options over there, i am attaching the screen shot of the editor it has the option for attaching image through URL but i need to upload file from my local.

please help me in this, thanks in advance.
