draw.current = new MapboxDraw({
displayControlsDefault: false,
styles: drawingStyle,
modes:
{
...MapboxDraw.modes,
[MapConstants.drawingTypeOption.freehand]: FreeDraw,

the 'ctx' object missing events

add this line to solve this problem:
```
ctx.events = events(ctx);
```

Open src/setup.js and reproduce the initialization shown in the issue, focusing on the ctx object and the getMode call before the control is added. Verify that the reported undefined-property error no longer occurs and that the initialization remains compatible with the custom modes.
