Uncaught TypeError: e.extend is not a function

Hello, after installing plugin via npm, it throws me error:

    at install (index.js:75:22)
    at Object.use (runtime-core.esm-bundler.js:4331:21)
    at main.js:33:5

in my main.js is:

import VueImg from 'v-img';

const vueImgConfig = {
    // Use `alt` attribute as gallery slide title
    altAsTitle: false,
    // Display 'download' button near 'close' that opens source image in new tab
    sourceButton: false,
    // Event listener to open gallery will be applied to <img> element
    openOn: 'click',
    // Show thumbnails for all groups with more than 1 image
    thumbnails: false,
  }

app.use(VueImg, vueImgConfig);
app.mount('#app')

I believe this is due to a lack of support for Vue 3
