getExecutionContext() is removed from DataFetchingEnvironment from Version 12 Onwards

As part of out project we are using DataFetchingEnvironment.getExecutionContext().getInstrumentation() to get ExecutionContext and respective Instrumentations chain to update the UsageState as per the requirement. Its all working fine till 11.0 version, but from 12.0 onwords ExecutionContext is been removed from DataFetchingEnvironment class and I am trying to find the alternate to get ExecutionContext so that I can retrive Instrumentations instance from it. I don’t see any replacement of this methods in Mmigration guide. Please help me if anyone came across this and have any solution.

Thanks is Advance.
