Agora video call application using laravel api backend and Vue js front end

I'm using Agora for my video calling, I followed the documentation and the screen on the front end is blank, which doesn't show anything. The only examples I have are those of that the vue js is working on the backend. haven't found anything with API and vue js. What should I do? Move the project to vue js back end or if I can get assistance from someone, so we find the cause.
