It mentions on the plugin site that all PennyLane operations are supported. https://amazon-braket-pennylane-plugin-python.readthedocs.io/en/latest/devices/braket_local.html#supported-operations

While running the QuantumPhaseEstimation template from Pennylane on the local device, this error is raised:

Thank you for the issue, and good catch; that documentation is out-of-date. We have since added new operations to the plugin, such as GPi and MS. As well, PennyLane added several new operations, and the plugin doesn't support all of them (for example, ControlledQubitUnitary). If your use case allows it, you'll need to use QubitUnitary with the full matrix of the controlled operation.
