Code Mirror in Perchance?

Hello everyone, did anyone try to use Code Mirror 5 or Code Mirror 6 to design a custom Editor for the perchance Text Generation?

I tried to import Code Mirror 5 with src in java script. I can run it without problem, but if I try to save it, there is an error.

Does anyone know what is the correct way to use code mirror in perchance?

Thanks in advance! :-)

PS.: ohh my god.. I wanted to add the code and the error message, but an error appears here to when I try to post it with the code... what is it about posting a code example of a code mirror import?
