Ruling on one who catches up with the tashahhud with the imam in Eid prayer or prayers for rain

What is the ruling on one who catches up with the tashahhud with the
worshippers in Eid prayer or prayers for rain? Does he have to pray
two rak'ahs as the imam did or what should he do?.
Praise be to Allaah.
If a person catches up with the tashahhud only with the imam in Eid
prayer or prayer for rain, he should pray two rak'ahs after the imam
says the salaam, doing in them as the imam did of takbeer, recitation,
bowing and prostrating.
And Allah is the source of strength. May Allah send blessings and
peace upon our Prophet Muhammad and his family and Companions. End
