Web Dynpro ALV - get Columns of selected Variant

Question

hi folks,
we use the personalization manager to set a start-up variant for displaying data in WD Abap ALV.
However, now we need the possiblity to get the columns shown on the screen (of that variant).
Using the functions like
  lr_column_settings ?= wd_this->go_table.
  lt_columns = lr_column_settings->get_columns( ).
on my config-table i always get ALL columns in the order of the Table i submitted to the ALV component.
What we need is as mentioned above to get the columns in order that are on the screen at the moment (or of that variant).
does anyone has a hint for me how to do that.
kind regards,
oliver

Thanks Oliver for the quick reply,
I tried the below code I am getting the variant right, but not the columns associated with the variant.
I get all the columns. Please check if I am missing anything,
      DATA lo_INTERFACECONTROLLER TYPE REF TO IWCI_SALV_WD_TABLE .
      lo_INTERFACECONTROLLER =   wd_this->wd_cpifc_em_list_alv( ).
      data: lo_api_interfacecontroller type ref to IF_WD_CONTROLLER,
            lo_pers TYPE REF TO if_wd_personalization,
            lt_pers_table_ref TYPE REF TO IF_WD_PERS_TABLE,
            lt_pers_table TYPE STANDARD TABLE OF WDR_PERS_DATA.
      lo_api_interfacecontroller = lo_INTERFACECONTROLLER->wd_get_api( ).
        CALL METHOD lo_api_interfacecontroller->get_personalization_manager
          RECEIVING
            pers_manager = lo_pers.
        DATA: ls_config_key type WDY_CONFIG_KEY,
              ls_PERS_SCOPE TYPE WDR_PERS_SCOPE,
              ls_loaded TYPE WDY_BOOLEAN,
              ls_desc TYPE WDY_MD_DESCRIPTION.
        CALL METHOD lo_pers->GET_STATE
          IMPORTING
            CONFIG_KEY  = ls_config_key
            PERS_SCOPE  = ls_PERS_SCOPE
            IS_LOADED   = ls_loaded
            DESCRIPTION = ls_desc. -> Gives me the Variant info
      data: ls_param_in type if_salv_wd_table=>s_type_param_config_in,
            lv_s_param_out TYPE if_salv_wd_table=>s_type_param_config_out,
        LS_r_model type ref to cl_salv_wd_config_table.
      ls_param_in-action = if_salv_wd_table=>set.
      ls_param_in-config_key = ls_config_key.
      ls_param_in-is_model_requested = 'X'.
      lv_s_param_out = lo_interfacecontroller->get_config_data(
        s_param_in =  ls_param_in                    
    LS_r_model = lv_s_param_out-r_model.
      data: lr_column_settings type ref to if_salv_wd_column_settings,
            lt_columns TYPE STANDARD TABLE OF SALV_WD_S_COLUMN_REF.
      lr_column_settings ?= LS_r_model.
      lt_columns = lr_column_settings->get_columns( ). -> this gives me all columns, not columns associated to variant
