VueJS client to retrieve Youtube Data API authorization

For an app I'm working on with a Vuejs front end, I would like to get a vuejs client (component/views) to retrieve user's authorisation information to upload videos to a youtube channel and send those authorisation information to the application backend. Application backend will then use this authorisation to upload videos. **Connecting to the application backend and the application backend are not part of this job** User flow: - From a simple page with a button labeled "authorised" the user can start the authorisation process - It opens a popup to go though the google authorisation process with Google Youtube Data API V3 and scope "[login to view URL]". - Then the user is sent back to a view to retrieve and display information from the authorisation callback It is important to note authentication is not needed, user would be already authenticated in the application using firebase authentication and 1 user could retrieve YouTube authorisation for multiple channels, once at a time (going through the authorisation process for each channel). The code should use only vuejs and no jquery. No design required. As a scanning question, please write in your answer the scope of the api authorisation mentioned in the description of this job. Please also provide a quote for the job,
