Who among the following historical figures formally became a member of Akbar's religious syncretism order, the 'Din-i-Ilahi'?

Raja Birbal (Mahesh Das) was the only prominent Hindu courtier to accept Akbar's new syncretic faith framework, the Din-i-Ilahi (Tauhid-i-Ilahi), which was introduced in $1582\text{ CE}$ to integrate moral elements from different religions. Other leading Hindu officials, such as Raja Man Singh and Raja Todar Mal, declined to join.
