prometheus go code is changed after upgrading from 2.11.1 to 2.23.0

Hi,

I was using prometheus promql in my go code for prometheus 2.11.1.

For eg: promql.ItemADD , promql.ItemSUB because the code structure was like this 

https://github.com/prometheus/prometheus/blob/v2.11.1/promql/lex.go

After upgrading to 2.23.0 the structure is changed to 

https://github.com/prometheus/prometheus/blob/v2.23.0/promql/parser/lex.go

I thought i could work with just changing the promeql to parser it'll work but that's not the case. The way code is written is also changed.

Can anyone tell me what's the equivalent of  promql.ItemADD in prometheus 2.23.0
