Do I need to send my dad and his girlfriend a photo of my notification of residence for their visit to Thailand?

Hello, my dad and his girlfriend will be visiting me (in Nahkon Ratchasima) for 2 weeks in December. I have booked accommodation in other provinces, but they will first come home with me for 3 nights before we travel further. Should I be sending them a photo of my notification of residence to avoid any problems upon entry? How can I ensure a smooth-as-possible immigration check for them? It's their first time leaving South Africa. 🙏🏼
