Theatre.js : how to animate multiple objects?

Hello everybody,
I have followed this example by @lexxik to use theatre.js in playcanvas. ( [PlayCanvas 3D HTML5 Game Engine](https://lexxik example: theatrejs + pc) )

I understand the logic to animate one object but now I would like to programmatically add any entity which has a particular tag to theatrejs studio so I can animate them easily.

for example let’s say I have 4 different models (box/cube) and I give them the tag “anim”

 // I get all my 'tagged objects'    

        const entities =this.app.root.findByTag("anim");
        // [...] I skip the basic theatrejs stuff [...] //

  // I create a "sheet" containing each objects and theirs props with this function
 
    function addObjtoSheet(obj){
       const getPropVec3 = (precision) => {
        return {
            x: t.number(0, { nudgeMultiplier: precision }),
            y: t.number(0, { nudgeMultiplier: precision }),
            z: t.number(0, { nudgeMultiplier: precision }),
        };
    };    
    return sheet.object(
        obj.name,
        {
            position: getPropVec3(0.01),
            rotation: getPropVec3(0.01),
            scale: getPropVec3(0.01),
            visible: true
        }
    );
    var objects=[];
    for (var i=0; i<entities.length;i++){

        objects.push(addObjtoSheet(objets[i]));
 
    }

  // their I (should) have my "theatre js sheet" with all my objects 

  console.log(objects)
}

But then I don’t know how to animate them and assign each object in the sheet to a “reel” entity in my scene ? If someone knows how I would love some help. Thanks
