How can I access a JWT token implicitly in .Net Core 2.1?

Question

I'm starting to learn about JWT and developing an angular app which uses Firebase to authenticate users.

Since the JWT token is sent in requests that need to be authorized I was wondering if I can access it and decode it somehow without explicitly setting it as a parameter?

Here is some code that uses JWT for Authorization

[HttpPost]
[Authorize(Policy = Policies.Admin)]
public async Task<IActionResult> CreateVehicle([FromBody]SaveVehicleResource vehicleResource)
{
        //How can I access the JWT token and decode it to get the user uid?
}
