If you decide to reply, it is suggested to reply by SMS or email to show that you have seen the information and thank you for it. You can simply reply "Thank you for reminding me" or "I received it, and I will deal with it immediately after going to work tomorrow", which can show that you have seen the information and will reply at an appropriate time.
If you don't reply, don't feel too worried or blamed, because after work is your private time, you have the right to choose whether to reply or not. However, if you find that you often need to work overtime, or handle work affairs outside of work, you can communicate with the leaders and seek suitable solutions.
