Development, no changes are applied

Development workflow of my plugin

  1. instaled mattermost in virtual
  2. clone there demo plugin to /root/mattermost-demo-plugin
  3. npx webpack --watch --progress --mode development
  4. this makes /root/mattermost-demo-plugin/webapp/dist/main.js always fresh, and all changes is there
  5. i delete /opt/mattermost/plugins/com.mattermost.demo-plugin/webapp/dist/main.js and create symbolic link to development version of main.js

but in browser i dont see any changes, even if it is checked that main.js includes this changes

can you help me? is something wrong with my workflow? if i restart mattermost, plugin is probably reloaded from installed zip?

thanks for help
