Does anyone know how to save audio messages from Facebook messenger?

Does anyone know how to save audio messages from Facebook messenger?
Tomorrow or the next day I will be receiving my new iPhone Pro Max and I would like to know if there is a way for me to save some audio messages I've got on Facebook messenger.
These are some audio messages that my three year old granddaughter has left me and I definitely would love to save them but I don't know if there is a way and or if there is a way to do it.
I would really appreciate any help you guys can give me.
Thank you all in advance.
Have a wonderful day.
Regards,
Raúl Valdez
