"ismethod" on restricted methods

i have class A with a method which is restricted to only be accessible by class B. When i am in class B i want to make sure that class A has this method. "ismethod" however does not work since the method is restricted. I think there should be some way to do this, since i am able to run the method from within B. I could do this with try & catch, but there must be a nicer solution to this.
% class A
classdef classA
methods (Static, Access = ?classB)
function method1
disp("hello, this is method1")
end
end
end
% class B
classdef classB
methods (Static)
function flag = CheckForMethod1(anotherClass)
flag = ismethod(anotherClass, 'method1'); % = false
anotherClass.method1; % this works
end
end
end
% Main
A = classA;
B = classB;
B.CheckForMethod1(A) % should return true, but returns false

This works
function flag = CheckForMethod1(anotherClass)
mc = metaclass( anotherClass );
flag = ismember( 'method1', {mc.MethodList.Name} );
anotherClass.method1; % this works
end
The function, ismethod, is restricted to public methods by design - I guess.
