mapboxgl.accessToken is cleared after initialize DeckGL

[fifzteen]

I make a pen for an another Question. using the deck.gl scripting API.
After new DeckGL, mapboxgl.acccessToken is cleared.

Enter your accessToken, and watch console.
From "create deck" accessToken is "no-token".
Is the way to init DeckGL without clearing accessToken exists?

The DeckGL scripting interface creates a Mapbox map automatically: https://deck.gl/docs/api-reference/core/deckgl#properties

If you don't want to use this convenience feature then construct a Deck instance instead.
