Etiquettes of correcting Imam mistake (in recitation) during Salah?

Question Does anyone know where I can find details on the etiquettes of correcting a mistake (in recitation) during Salah? Answer: ﺑﺴﻢ اﷲ اﻟﺮﺣﻤﻦ اﻟﺮﺣﯿﻢ In the name of Allah, the Most Gracious, the Most Merciful

There are some etiquettes mentioned in Umdatul Riayah which is the hashiya (commentary) of Sharhul Wiqayah in the chapter of Salah; That Which Invalidates the Prayer and What is Disliked Therein. [1]

Only Allah knows best
