Dua for Thanking someone in islam

We have seen that the believer never expects gratitude or recompense from anyone who benefits him. On the other hand, it is the duty of the beneficent believer to express gratitude to the benefactor, to praise him, to openly acknowledge his beneficence, and to pray for him. The Prophet (ﷺ) said: If someone does good to someone and he gives thanks to the benefactor by saying this, then it will be best appreciated.
