How to use the kpc/components/message.info function in kpc

it('set duration', async function() {
        this.enableTimeouts(false);

        Message.info('test', 500);

        const message = getElement('.k-message');
        expect(message.outerHTML).to.matchSnapshot();
        // should not remove when mouseenter
        dispatchEvent(message, 'mouseenter');
        await wait(1000);
        let message1 = getElement('.k-message');
        expect(message1).eql(message);

        dispatchEvent(message, 'mouseleave');
        await wait(300);
        message1 = getElement('.k-message');
        expect(message1).eql(message);

        await wait(700);
        message1 = getElement('.k-message');

_fetch1(c, current) {
        // fetch data
        this.set('current1', current);
        Message.info(`current page: ${current}`);
    }

cancel() {
        Message.info('Clicked cancel!');
    }
}

_fetch2({current, limit}) {
        Message.info(`current page: ${current}, limit: ${limit}`);
    }
}
