How to implement redo of draw interaction in openlayers?

Question

In the case of undo, this is implemented using drawInteraction.removeLastPoint().

But I don't know how to implement redo.

The redo function should be available when drawing interaction is active.

Should I use "setGeometry"?

I found append Coordinates in openlayers api.

drawinteraction.appendCoordinates([coordinate]);
