How to properly compile vue component with vuex?

Question

Vue.js

Good afternoon.
There is a ready-made chat component that should be embedded into the application, as a library https://cli.vuejs.org/guide/build-targets.html#library .
1) I compile the component "vue-cli-service build --target lib --name chat ./src/components/Chat.vue;
2) I move chat.umd.js into the application in the @/modules/chat_module directory
3) On startup the project throws an error in the browser TypeError: Object(...) is not a function

The module itself is written in vue3, the project uses vue2.The component also uses vuex and typescript.The entry point is specified as

./src/components/Chat.vue.Who Has anyone experienced this and how would you solve this problem?
