Reply To: SVG Icon and Menu Layout

Add on from my question 1:
i have seen another forumer post about same problem and the solution was to edit the svg icons in editor and add the code: https://gyazo.com/83fd36b0bb9628bb1aed2bd3d5d063c5

However, after i have done it and tried to reupload it, WordPress does not allow me to as it said the svg icon cannot be sanitised. How to resolve this?

Thanks
