How to apply chalk pastel on baked polymer clay?

I'm learning new methods for my polymer clay pieces. I follow thelittlemew instagram and see that she baked her pieces before adding chalk pastel. I tried to do the same but the pastel wouldn't stick to my baked clay. Does anyone here know how she put pastel on baked clay? Thank you very much. I will appreciate every answer.
