.SYNOPSIS
Authenticates with Spotify API using OAuth flow to obtain an access token.

authentication flow. Once authenticated, retrieves and stores the access token for
subsequent API calls. The browser window automatically closes after successful
authentication. Uses port 5642 for the OAuth callback listener.
 
.EXAMPLE
# Authenticate with Spotify and obtain access token
Connect-SpotifyApiToken
 
.NOTES
Uses port 5642 as the default callback port for OAuth flow
Minimizes browser window during authentication
Automatically closes browser window after successful authentication
