Unsichtbarer Button wurde nun ersetzt durch einen ReactFlowProvider (App ist wrapped) und den folgenden useEffect in der Topic page

useEffect(() => {
    if(initialNodes) {
      setTimeout(() => {
        fitView({
          padding: 5,
          minZoom: 0.75,
          duration: 100,
          nodes: [{ id: initialNodes[0].id }]
        })
      }, 100)
    }},[topicId])
