I believe it was Wasim Akram, not Imad Wasim, who was not selecting him for playing xi of KK. Wasim Akram is bashing Rizwan since long and its obvious that either he does not like him personally or he is not impressed by his cricket. While doing commentary in Pakistan vs Australia test series (2019), he was quite annoyed (in fact angry) about Rizwan speaking Pashto behind the stumps. In England vs Pakistan test series, while English commentators were praising Rizwan, Wasim Akram was bashing him for talking too much behind the stumps. Then in November 2020, he rather harshly rebuffed the option of Rizwan being test captain, he bluntly stated that Rizwan does not deserve to be a test captain, that the latter has not even established his place in the team (which he actually has).
