Grommet DataTable Only allow Single select - reactjs

Question

Does Grommet have a built in solution to only allow single or multiple selections within a dataTable? I came up with this useState function that clears the array before setting it but it has an adverse reaction of forcing the user to click twice. If array > 1 user clicks which sets the select array to [] forcing the user to click again.
import React from "react";
import ReactDOM from "react-dom";
import {Grommet, DataTable, Text, Meter, Box} from 'grommet';
const GridExample = () => {
const [select, setSelect] = React.useState([])
function handleRowSelect(selection) {
console.log(`You picked ${selection}`);
if (selection.length > 1) {
setSelect(selection[selection.length - 1].toArray)
} else {
setSelect(selection)
}
}
return (
<Grommet>
<DataTable
select={select}
onSelect={handleRowSelect}
columns={[
{
property: 'name',
search: true,
header: <Text>Name</Text>,
primary: true,
},
{
property: 'percent',
search: true,
header: 'Complete',
render: datum => (
<Box pad={{vertical: 'xsmall'}}>
<Meter
values={[{value: datum.percent}]}
thickness="small"
size="small"
/>
</Box>
),
},
]}
data={[
{name: 'Alan', percent: 20},
{name: 'Bryan', percent: 30},
{name: 'Chris', percent: 40},
{name: 'Eric', percent: 80},
]}
/>
<Text>Selected: {select}</Text>
</Grommet>
)
}
export default GridExample;
ReactDOM.render(
<GridExample/>,
document.getElementById("root")
);
Update: Using Slice in the function fixes the double click.
function handleRowSelect(selection) {
if (selection.length > 1) {
setSelect(selection.slice(-1))
} else {
setSelect(selection)
}
}

I don't think there is a built-in solution (for grommet 2.17.5).
Though, you can always try to manipulate select and onSelect in different ways, for example, one way for that will be to add a condition to onSelect and disable selection option once one row had been selected already:
onSelect={select.length < 1 && handleRowSelect}
This will make sure only one row is selected at any given point.
If you'd like the users to be able to reset their decision, you can always add a reset button that clears the array of selection, and the checkboxes will be enabled again.
