Resolved Adding Environment Probe manually

Does someone has code how to do that?
The EnvironmentProbeManager tells me to:

Code (CSharp):

1. /// <summary>
2.         /// Creates a new environment probe at <paramref name="pose"/> with <paramref name="scale"/> and <paramref name="size"/>
3.         /// if supported by the subsystem. Use the <see cref="SubsystemLifecycleManager{TSubsystem, TSubsystemDescriptor}.descriptor"/>'s
4.         /// `supportsManualPlacement` property to determine support for this feature. If successful, a new
5.         /// <c>GameObject</c> with an <see cref="AREnvironmentProbe"/> will be created
6.         /// immediately; however, the provider may not report the environment probe as added until a future frame. Check the
7.         /// status of the probe by inspecting its
8.         /// <see cref="ARTrackable{TSessionRelativeData,TTrackable}.pending"/> property.
9.         /// </summary>
10.         /// <param name="pose">The position and rotation at which to create the new environment probe.</param>
11.         /// <param name="scale">The scale of the new environment probe.</param>
12.         /// <param name="size">The size (dimensions) of the new environment probe.</param>
13.         /// <returns>A new <see cref="AREnvironmentProbe"/> if successful, otherwise <c>null</c>.</returns>
14.         /// <exception cref="System.InvalidOperationException">Thrown if this manager is not enabled</exception>
15.         /// <exception cref="System.InvalidOperationException">Thrown if this manager has no subsystem.</exception>
16.         /// <exception cref="System.NotSupportedException">Thrown if manual placement is not supported by this subsystem.
17.         /// Check for support on the <see cref="SubsystemLifecycleManager{TSubsystem, TSubsystemDescriptor}.descriptor"/>'s
18.         ///     `supportsManualPlacement` property.</exception>
19.         [Obsolete("Add an environment probe using AddComponent<" + nameof(AREnvironmentProbe) + ">(). (2020-10-06)")]

But I have nio idea how to dio this.
There is the comment: [Obsolete("Add an environment probe using AddComponent<" + nameof(AREnvironmentProbe) + ">(). (2020-10-06)")]

Does this mean I need to use the AREnvironmentProbe component?
How do I check if the subsystem supports manual placement?
