exposeprivatechannels is missing in cln-grpc InvoiceRequest

[JssDWt]

In the node.proto in the source code of cln v22.11.1, there's a field called exposeprivatechannels on the InvoiceRequest. It is missing in v23.05.1.

v22.11.1:

lightning/cln-grpc/proto/node.proto

Line 584 in b3a1d01

optional bool exposeprivatechannels = 8;

v23.05.1: https://github.com/ElementsProject/lightning/blob/v23.05.1/cln-grpc/proto/node.proto#L589-L598

How do I, over grpc, make a request for an invoice that includes private channels in the hop hints?
