While this plugin did work with bedrock clients before It did so with the issue of flickering titles.
This is a client side bug that cannot be fully resolved.
this update does it's best to address this by allowing you to set the frequency of title/action bar updates to a higher number.

When set to 1000 (1 second) The flicker is only noticeable every second.
To set this see: "update-rate" in config.yml
