Grover assumes type GroverOperator

	max_power = np.ceil(
	2 ** (len(amplification_problem.grover_operator.reflection_qubits) / 2)
	)

it simply accesses reflection_qubits on what was passed to the AmplificationProblem as a grover_operator

grover_operator: QuantumCircuit | None = None,

but this is of type QuantumCircuit which does not have that field - only the GroverOperator subclass does. This should be more dynamically taken care of such that if a QuantumCircuit is passed, without that field, that it is handled accordingly.
