What Basket Strainer waste I need for This Ceramic Sink?

[wau5]

I got this sink
https://www.ebay.co.uk/i/282116995185

Somehow it didn't came with the basket strainer waste, I bought this one
https://www.toolstation.com/shop/Plumbing/d20/Sink+Wastes+&+Traps/sd3299/Stainless+Steel+Basket+Strainer+Waste/p16490
However it does not fit it as seems like its made for metal sinks + it's very flimsy,
Anyone knows what kind of strainer waste does this sink needs and where I can get one? (with a square overflow)

Thanks.

Couple here that look much more sturdy:

These two specifically say they are for ceramic sinks, they are advertised as 40mm waste so will be made to metric standard, this can sometimes be an issue when you have a trap that is actually 1.5" as they aren't exactly the same but shouldn't cause too much of a problem connecting to new traps.
