How do I add a snippet of the code?

[N23Dev]

Hello, 

I would like to know how I can add code insertion such as web languages to Affinity Publisher?

Because I have to prepare the tutorials for the creative guides for my clients. 

Thank you very much, 
Best regards

For text probably by copying over preformated code text, in the hope that then the indents and possibly keyword colorings etc. are kept persistent during that copy operation. Another thing to try out may be to import preformated code from docx or PDF format. - Other than that if nothing works with text and in trouble, use captured image portions of snippets.
