Draw Routes between 2 points on offline status

[FashionCStar]

I have downloaded offline packs for specific areas.
And after set offline, I want to draw the routes between 2 points in the downloaded pack

I found this document from the mapbox SDK docs
https://docs.mapbox.com/android/navigation/guides/offline-service/

How could I use this feature in react-native-mapbox-gl?

      const res = await directionsClient.getDirections(reqOptions).send();
      this.setState({
        route: makeLineString(res.body.routes[0].geometry.coordinates),
      });

directionsClient.getDirections() function works well on online status, but getting error {isTrusted:false} on offline status.

The Navigation SDK is not included in our project.

Please see here for the packages we include (and support):

import MapboxDirectionsFactory from '@mapbox/mapbox-sdk/services/directions';

const clientOptions = {accessToken: 'pk.eyJ1IjoiZmFzaGlvbmRldjEiLCJhIjoiY2tscjlmM3diMTNkaTJvbnc1OXBpbzVwNiJ9.yJIaRGA7FoRXjQCSPj3WEA'};
const directionsClient = MapboxDirectionsFactory(clientOptions);
const res = await directionsClient.getDirections(reqOptions).send();
this.setState({
    route: makeLineString(res.body.routes[0].geometry.coordinates),
});

Of course, I am using mapbox-sdk to get directions.
But it doesnt work on offline status
