Is Sujud Al-Sahw (prostration of forgetfulness) required when repeating the Takbir of الانتقال (transitioning between prayer postures) in prayer?

It is prescribed for one who inadvertently adds an extra takbir or tasbih in their prayer to perform the two prostrations of forgetfulness (sujud al-sahw) after the salutation (taslim), as an atonement for that addition. This is done by way of recommendation, not obligation.
