What tool to tighten this bath waste

[williamglossop]

Does anyone know what tool I would need to tighten this bath waste? I think it came with a plastic tightening tool, but that was 5 years ago

This is it with the top screwed on. This chrome dome unscrews and this is under it....

From memory, the whole central white plastic thing rotates to tighten it.

Do you mean something like this:

Monument Pop Up Waste Installation Tool - MON325L | Tap & Sink Tools | Toolchimp (monumenthandtools.co.uk)

I imagine you could also use needle nosed pliers.
