Motion Capture Retargeting to Metahuman

Hello, I hope someone can help me. For a university project, I am recording motion capture animations with the Optitrack Motvie Software. I want to retarget them to a metahuman in UE 5.3 and I am following this tutorial https://www.youtube.com/watch?v=VuJf3jCEs2o&t=1152s

Everything worked fine. but at minute 19 I couldn’t follow the tutorial anymore because the metahuman blueprint in the tutorial is totally different then mine (see pictures). My metahuman blueprint misses the function RetargetSetup. Does anyone know why that is? Do I have to enable something?


Thank you for your help. I hope there is someone who can help.
