Strapi-plugin-multi-select

Has anyone using this plugin, mine is not working. Facing a register error in it.

My strapi version is 4.3.8.

Has anyone got any solution, I really want to implement this in my project.

If that is that plugin is says 4.4+ Multi Select Input | Strapi Market

I’ve upgraded my version of strapi to 4.4.0, this plugin is installed but not showing in the Content-Type Builder.
Any solution for this?
