Morph Mod/Addons

Hello,I'm pretty new to minecraft and play with my daughter (and whenever I can without her too!) She watches you tube video's of minecraft streamers and has her heart set on a morphing mod that she saw one of them use. I have looked into getting a mod but it seems to be that the launchers that they need are for the Java edition, how do I find/get/use addons on the windows 10 store version? (Bedrock??) I hope some one can point me in the right direction!

Cheers, Triscall ¤
