Using YouTube Data API to upload videos only with OAuth 2.0 - google-api

Question

For the context: I am building a React App that allows users to upload an MP3 file and an image. Both these files get rendered to an MP4 file through FFmpeg on the client side (in React). I then want to let the user upload the result to YouTube.
So technically everything executed on the YouTube API comes from the user and isn't made through any server. How would I go about uploading the video without having an API Key, just having an OAuth 2.0 object from the user that signed in and that wants to upload the processed video to their channel?
The main problem is that generally a YouTube user has a quota of 50 uploads per day that can be made use of but if I follow YouTube's docs I'd have to upload the videos through a Google Cloud Project Client (which gives me an API Key) and said client would have a predefined quota for all requests (which is about 2 videos per day). Now that's not what I want, through using a client my entire app would only have 2 uploads per day and not 50 uploads per day per user.
Does anyone have experience with such a problem or an idea on how I could work this out?

Uploading or inserting videos in to YouTube requires that you be authorized. What you do is send an authorization header with a bearer token as shown below.
curl --request POST \
'https://youtube.googleapis.com/youtube/v3/videos \
--header 'Authorization: Bearer [YOUR_ACCESS_TOKEN]' \
--header 'Accept: application/json' \
--header 'Content-Type: application/json' \
--data '{}' \
--compressed

This is actually a hard limit imposed by YouTube itself it is not related to the api you are using. No one can upload more than 50 videos a day.
if I follow YouTube's docs I'd have to upload the videos through a Google Cloud Project Client (which gives me an API Key) and said client would have a predefined quota for all requests (which is about 2 videos per day).
Im not sure where you read this can i have a link to that doc?
First off api keys are used when accessing public data, for example public videos stored on youtube. you could do a video.search with an api key you dont need an access token. What it does is identify your project to google so it knows which project to deduct the quota from. But an access token does exactly that so you dont need both. In your case inserting a video you dont need an api key for that.
To be clear an api key should not give you access to insert a video as it can only access public things. IT cant upload to a privet user account with out permission and an api key has no permission.
