How to map snare drum side stick to a new tom-tom technique (side click) in Dorico

I created a tom tom technique - side stick for my percussion kit. However, the playback sound is still like a normal tom tom (high) sound. I think that the snare drum side stick can imitate the sound of side stick on tom tom (high). How can I do it?

I watched some videos on Youtube, but I still do not know how to make it step by step. Could anyone help me please? I was a finale user. This is pretty new to me. Thank you so much!
