Having issues with projects that use Vue2 and do not use the composition api. Do I need to make it compulsory in my package?

Here's my package.json

{
  "name": "vue-supabase",
  "version": "1.0.4",
  "description": "A small wrapper for integrating supabase to Vuejs",
  "main": "index.js",
  "engine": {
    "node": ">= 1"
  },
  "scripts": {
    "test": "npm run test"
  },
  "repository": {
    "type": "git",
    "url": "git+https://github.com/scottrobertson/vue-supabase.git"
  },
  "keywords": [
    "vue",
    "custom",
    "supabase"
  ],
  "author": "Scott Robertson",

  "files": [
    "index.js",
    "index.d.ts"

  "dependencies": {
    "@supabase/supabase-js": "^1.4.2",
    "vue-demi": "^0.11.2"
  },
  "peerDependencies": {
    "@vue/composition-api": "^1.0.0-rc.1",
    "vue": "^2.0.0 || >=3.0.0"
  }
}

And here's my index.js

'use strict';
Object.defineProperty(exports, '__esModule', { value: true });

const { inject, isVue3 } = require('vue-demi');

const { createClient } = require('@supabase/supabase-js')

const supabaseKey = 'supabase';

function useSupabase(key = null) { 
  return inject(key !== null ? key : supabaseKey);
}


exports['default'] = {
  supabaseKey,
  useSupabase,
  install: function (app, options) {
    const supabase = createClient(options.supabaseUrl, options.supabaseKey, options.supabaseOptions)

    app.provide(supabaseKey, supabase);

    if (isVue3){
      app.config.globalProperties.$supabase = supabase;
    } else {
      Object.defineProperties(app.prototype, {
        $supabase: {
          get: function() {
            return supabase;
          },
        },
      });
      app.supabase = supabase;
    }
  }
}

module.exports = exports['default'];

This is from a branch of a vue-supabase fork. It works for vite and vue3 but not for Vue2 using @vue/cli to create the project https://github.com/sduduzog/vue-supabase/tree/use-vue-demi
