const fxl::WeakPtr< ::a11y::SemanticTree> Get ()Returns a weak pointer to the Semantic Tree owned by this service. Caller
must always check if the pointer is valid before accessing, as the pointer
may be invalidated. The pointer may become invalidated if the semantic
provider disconnects or if an error occurred. This is not thread safe. This
pointer may only be used in the same thread as this service is running.

zx_koid_t view_ref_koid ()Returns the View Ref Koid of the semantics provider connected to this service.

void EnableSemanticsUpdates (bool enabled)Calls OnSemanticsModeChanged() to notify semantic provider whether Semantics Manager is enabled
or not.
Also, deletes the semantic tree, when Semantics Manager is disabled.
