Can I assist my mom with her international flight boarding if I’m flying domestic on the same day?

Hey everyone, My mom and I are both departing from Hyderabad airport on the same day, and our flights are almost at the same time. Her flight is an international one, while mine is a domestic flight. Since her flight is scheduled first, can I assist her with her boarding process and then proceed to my own flight? Would love to know if this is possible or if there are any restrictions I should be aware of. Thanks in advance!
