MQTT QoS 1 Queue name

Hi,
we are using a sap netweaver system with
SAP_BASIS 745 and SP-Level 0005
SAP_ABA 75E and SP-Level 0005
There is implemented a mqtt interface and in class CL_MQTT_CLIENT and method IF_MQTT_CLIENT~CONNECT there is no support for clean session false.
ABAP code ---------------------------------------------------------------------------------------------------------------------
  CALL METHOD cl_mqtt_krn_services=>mqtt_connect
    EXPORTING
      i_apc_client_conn_id       = lv_apc_client_id
      i_timeout_ms               = lv_mqtt_connect_timeout
      i_mqtt_client_id           = lv_mqtt_client_id
      i_mqtt_clean_session       = abap_true  " no support for clean session = false yet !
ABAP code ----------------------------------------------------------------------------------------------------------------------
So that’s the reason i want to check the existence of an mqtt queue in the solace broker.
Best regards
Jens
