EMQX HA addon - any way to disable login for the UI?

I really do not need authentication to log into the EMQX UI. Any way to disable it? I did look into documentation but didn’t find anything I could use with the addon. Tried

env_vars: []
  - name: EMQX_ALLOW_ANONYMOUS
    value: true

in the addon config yaml but it didn’t work.

Any tips? Thanks!
