How to pass data from the form from the modal window to the one who called this window?

Question

Vue.js

New to Vue. There is a modal window on Vue with 2 dropdowns and "OK" and "Cancel" buttons. Suppose there is a button, when clicked, this window should open, and if OK is selected, then take the values ​​​​from the dropdowns selected in the window and perform the calculations. If Cancel is pressed, do nothing.
Question: how to organize the transfer of data from the window to the one who called it? I read in the documentation that components can only send events. The OK button is selected -- the accepted event is called, if Cancel, then rejected. How would I do this to get the values ​​from the window if the OK button is pressed? Can use somehow Promise?
