How does the JS in vue refer to the methods method in .vue?

there is a method of refreshing CAPTCHA in methods of login.vue. In another JS, I want to refer to that method of refreshing CAPTCHA. How should I write it?

login.vue file

<template>

extract the js of refreshing CAPTCHA, import it through import, mix it with mixins,
use reference:
VUE project development using mixins


in js import login from'. / login.vue' ; Note that if necessary, you can print the login as a component object, console.log (login) , to see whether the login component has been introduced, and then the login.methods.refreshVerify () call indicates that the refreshVerify function under the login component has been called

if necessary.
