How to Set TX Power for Response Packets in periodic_sync_conn?

Question

HI 
 I am currently using the nRF54L15 chip with NCS 3.2.1, carrying out secondary development based on the periodic_sync_conn sample project. I intend to adjust the transmit (TX) power before the response data is reported. I have found that the function below can be called to modify TX power; however, this function only works for adjusting the TX power of the advertising broadcaster and has no effect on the TX power used for response transmissions. Which function should I invoke to configure the TX power specifically for response packets? 
 
 static void set_tx_power ( uint8_t handle_type, uint16_t handle, int8_t tx_pwr_lvl) 
 { 
 struct bt_hci_cp_vs_write_tx_power_level * cp ; 
 struct bt_hci_rp_vs_write_tx_power_level * rp ; 
 struct net_buf * buf , * rsp = NULL ; 
 int err ; 
 
 buf = bt_hci_cmd_alloc ( K_FOREVER ); 
 if ( ! buf ) { 
 printk ( "Unable to allocate command buffer 
 " ); 
 return ; 
 } 
 
 cp = net_buf_add ( buf , sizeof ( * cp )); 
 cp -> handle = sys_cpu_to_le16 (handle); 
 cp -> handle_type = handle_type; 
 cp -> tx_power_level = tx_pwr_lvl; 
 
 err = bt_hci_cmd_send_sync ( BT_HCI_OP_VS_WRITE_TX_POWER_LEVEL , 
 buf , & rsp ); 
 if ( err ) { 
 printk ( "Set Tx power err: %d
 " , err ); 
 return ; 
 } 
 
 rp = ( void * ) rsp -> data ; 
 printk ( "Actual Tx Power: %d
 " , rp -> selected_tx_power ); 
 
 net_buf_unref ( rsp ); 
 } 
 
 Thanks!
