1 1/5 bowl sink with Overflow

[IJWS15]

Daughter wants kitchen re-fitting and has bought a 1.5 bowl sink but it has an overflow in the half bowl.

All the drain kits I have found cover the 1.5 bowl but have no provision for the overflow

Where can I get a kit which can handle the overflow?

Thanks

Think I have answered my own question.

The overflow is part of the outlet that I fasten to the sink before I use the drain/trap kit . . .

both are basket wastes with overflow connections,
