Lyra - Ability that will change material on a character part

Hey guys,
I’m using the lyra starter project, and I have an ability that I want to change a material on the character parts. That is:

  1. My experience has Add Components action, where the actor=Controller , and the Component Class= MyCharacterParts
  2. MyCharacterParts has event of Event Begin Play, at which point it’s calling Add Character Part , adding BP Ettore (from MetaHuman).

Everything in the above is working great.

I now want an ability that will change a property in the components inside BP Ettore; That is, will change the way the character looks.

I belive I should do that using gameplay tags, so I can add tags to the player in the GA, but not sure how to listen for it in BP Ettore, mostly in terms of flow ?
