Look at the code from the link that I provided you.

this.tooltipServiceWrapper.addTooltip<LineDotPoint>(
     dotsSelectionMerged,
     (tooltipEvent: TooltipEventArgs<LineDotPoint>) => {
         return this.getTooltipDataItems(tooltipEvent.data);
    }
);

You just need to call method addTooltip and provide couple of arguments there.

The first argument is d3 selection that is a target for a tooltip.

The second argument is a callback function that has to return an array of objects that contain tooltip inforamation.

For instance, you could write even something simple like below to test how it works:

        this.tooltipServiceWrapper.addTooltip(
            warning.title, // target d3 selection, replace by your selection
            () => {
                return [{
                    displayName: null,
                    value: "some text that will be displayed in a tooltip"
                }];
            });
