Is it permissible for the ma'mum to recite the opening supplication if he recites al-Fatihah?

The questioner:
Honorable Shaykh, may Allah grant you success. He says: If I enter the prayer with the imam while he is reciting aloud, and I want to recite al-Fatihah during the imam's pauses, do I recite the opening supplication first and then al-Fatihah, or is the opening supplication dropped in this case?

The Shaykh:
The opening supplication is not obligatory. It is not obligatory, but they say you should recite it even if the imam is reciting aloud, because the imam does not cover the opening supplication for you, unlike al-Fatihah, which the imam covers for you. Yes.

The questioner:
Honorable Shaykh, may Allah grant you success, is the intention to recite al-Fatihah in the sunnah?

The Shaykh:
They said: He seeks refuge and opens with the opening supplication, he opens with the opening supplication and seeks refuge in what his imam recites aloud, because the imam does not cover the seeking of refuge and the opening supplication for the ma'mum, unlike al-Fatihah, for which the imam covers it for him. Yes.
