I tried to trigger the tooltip for a specific entry in a google chart when coming from a link from an external URL.

const urlParams = new URLSearchParams(window.location.search);
            const showTooltip = urlParams.get('showTooltip');
            if (showTooltip) {
                google.visualization.events.addListener(scatterChart, 'ready', function() {
                    setTimeout(() => {
                        showTooltipForEntry(showTooltip);
                    }, 1000);
                });
            }

function showTooltipForEntry(entryName) {
            const rowIndex = data.getFilteredRows([{column: 1, value: entryName}])[0];
            if (rowIndex === undefined) return; // If no matching row, exit

            scatterChart.getChart().setSelection([{row: rowIndex, column: null}]);
        }

The tooltip should show with the following URL: http://example.com/page?showTooltip=Identifier

The data point in the chart is selected, but the tooltip doesn´t show. The trigger for the tooltip is set to “both”. Any ideas on how to fix this?
