Using "HAL_CAN_AddTxMessage" from interrupt and main loop

Hi, I want to be able to add CAN message with "HAL_CAN_AddTxMessage" from interrupt and main loop (loop maybe busy sometimes so I cant send all messages from it). I assume they can collide and override so its not safe to do it from both?What are my o...
