How to apply frontend changes in this project?

I have modified the files under web/libs/editor/src/common, and expect to see some changes on the web.

Following the README files, what I have tried is to:
1. Rerun
```shell
python label_studio/manage.py migrate
python label_studio/manage.py collectstatic
python label_studio/manage.py runserver
```
2. Run
```shell
yarn ls:watch
# and
yarn lsf:watch
```

However, these commands seem didn't update my modification to the frontend page.
