Ho to call plugin inside component with composition api

[camohub]

According documentation I made a helpres.ts plugin file with translate method which I would like to use inside components.

import { useAppStore } from '@/store/app'

export default {
    install: (app) => {

        const appStore = useAppStore()

        app.config.globalProperties.$translate = (translations, key) => {

            let defaultTranslation = translations[key] ? translations[key][0] : ''  // First item as default value or ''

            const translation = translations.find((item, key) => {
                if ( item[key] && item[key].locale == appStore.defaultLang.val ) {
                    return true;
                }
            });

            return translation ? translation : defaultTranslation
        }
    }
}

Then I register plugin in main.ts this way

import helpers from './plugins/helpers';
app.use(helpers)

But documentation does not mention how to use plugins inside components. How can I call helpres.translate inside the code and inside templates?
