ALL VIDEO SHARE

I've been running on Joomla5 for a while with All Video Share 4.2.4, but I just realised that I have the backward compatibility plugin enabled, and if I disable it, I get the error shown below. Presumably I need to upgrade to a newer version? Will this version also be Joomla 6 compatible?
Thanks,

Attempted to load class "JComponentHelper" from the global namespace.
Did you forget a "use" statement?

Our latest release, version 4.3.0, is fully compatible with Joomla 6, as well as Joomla 5 without requiring the compatibility plugin.
Please update to the latest version of our extension, and it should resolve the issue you’re facing.
