Running callbacks to users not logged in

I have a plugin that generates objects to aid in workshops online and providing visual aids to them on Miro, the object creation itself is done by a logged in user, but I want to do some updates to a card object that are done by users who are joining in that are not logged in.

I just want to change the color and rotation of a card, is this possible?

I’ved added 

 

async function checkCardMovments( widget_id ){

        await miro.board.widgets.update({ id: widget_id, 
                                          rotation: 0,
                                          style: { backgroundColor: '#FCEEF0'} })

}

  miro.onReady(() => {
    miro.addListener('WIDGETS_TRANSFORMATION_UPDATED', (e) => {

        if( (e.data.length == 1) && ( e.data[0].type == 'CARD' ) ){
            checkCardMovments(e.data[0].id)
        }
    })
  }

to the miro.onReady of the js file that is initializing the plugin, it works fine if I am a logged in user but the callback doesn’t seem to run at all if its an anon user.
