Unable to delay between two roasts.

[SMARTMICROWORLD]

I want to display 2nd toast after delay of 8 sec, but below code is not working. How can i achieve that?

Toast.show({
type: 'infoToast',
text1: 'Hellow',
visibilityTime: 8000,
});
Toast.show({
type: 'tomatoToast',
text1: 'Hellow',
visibilityTime: 8000,
});

use setTimout(callSecndtaostFun,delay);
this will not be exactly 8sec but least 8 sec
