Use Animations from an external FBX file?

My setup is usually so that I have a character.glb file and then lots of different animations from one or multiple fbx files, which I apply on the character like this:

(this setup makes totally sense when you have multiple characters in a multiplayer game with small size and have only once to load all the animations for all players (since they are all the same right?):

 const {scene}= useGLTF("character.glb");
  const walkingFbx = useFBX("walking.fbx");
  const { actions } = useAnimations(walkingFbx.animations, characterRef);

  useEffect(() => {
    actions?.[Object.keys(actions)[0]]?.play();
  }, [actions]);
//..
 <primitive ref={characterRef} object={scene} />

how would I achieve this in this case:

  /**
   * Character url preset
   */
  const characterURL = './Demon.glb'

  /**
   * Character animation set preset
   */
  const animationSet = {
    idle: 'CharacterArmature|Idle',
    walk: 'CharacterArmature|Walk',
    run: 'CharacterArmature|Run',
    jump: 'CharacterArmature|Jump',
    jumpIdle: 'CharacterArmature|Jump_Idle',
    jumpLand: 'CharacterArmature|Jump_Land',
    fall: 'CharacterArmature|Duck', // This is for falling from high sky
    action1: 'CharacterArmature|Wave',
    action2: 'CharacterArmature|Death',
    action3: 'CharacterArmature|HitReact',
    action4: 'CharacterArmature|Punch'
  }
//...

 <EcctrlAnimation characterURL={characterURL} animationSet={animationSet}>
                  <CharacterModel />
 </EcctrlAnimation>

Do I need to manipulte the EcctrlAnimation.tsx by myself?

export function EcctrlAnimation(props: EcctrlAnimationProps) {
  // Change the character src to yours
  const group = useRef();
   const animations= useFBX("allmyAnimationsIn1FBX.fbx"); //here?
  const { actions } = useAnimations(animations, group);

Start with EcctrlAnimation.tsx and trace how characterURL, animationSet, useFBX, and useAnimations currently connect. Check whether an external FBX animation source can drive the supplied character while preserving the named animation actions. Done means the documented component usage can load animations separately from the character model and play the configured set.
