How to import/export RTF file content to the editor?

[KiddoV]

How do I import rtf file content into the editor?
For example:

{\rtf1\ansi\ansicpg1252\deff0\nouicompat{\fonttbl{\f0\fnil\fcharset0 Calibri;}}
{\colortbl ;\red155\green0\blue211;}
{\*\generator Riched20 10.0.19041}\viewkind4\uc1 
\pard\sa200\sl276\slmult1\cf1\b\f0\fs22\lang9 Testing RTF\cf0\b0\line This is an RTF content...\line\i Hello\i0\par
}

After editing, how do I export the content out as rtf raw string?

I guess you will need some way to parse RTF content to html/plain text in order to import them to Quill since Quill doesn't provide a built-in way.
