How can I show existing feature in Map with this editable properties?

[Masoud-kamali]

I can show my existing feature in the map, but it has no editable form such as pan, uncombine or etc. which exist in draw control.
actually I can not access
get(featureId: string): ?Feature,
getFeatureIdsAt(point: { x: number, y: number }): Array,
etc
which is existing in mapbox-gl-draw
