The Netflix series, based on the horrific 2012 Delhi gang-rape, became India's first web series to win an International Emmy Award.
According to Shefali, the team has made her "better, richer, happier and fuller as an actor and more so as a person."
The Mumbai-set film, also starring Shefali Shah, Vijay Verma and Roshan Mathew, is mounted against the backdrop of a conservative lower middle-class neighbourhood.
Directed by Anubhuti Kashyap, the film features Shah as senior doctor Nandini opposite Ayushmann Khurrana and Rakul Preet Singh.
With Vidya and Shefali in the lead, the 'Jalsa' cast also features Rohini Hattangadi, Iqbal Khan, Vidhatri Bandi, Gurpal Singh, Surya Kasibhatla and Manav Kaul.
On Thursday, Shefali took to her Instagram account and posted a string of images from the wrap-up celebrations.
Shefali Shah’s new directorial, Happy Birthday Mummyji, will release on July 23 on Large Short Films.
Directed by Anubhuti Kashyap and backed by Junglee Pictures, the film also stars Rakul Preet Singh and Shefali Shah.
Shefali's post garnered several likes and comments as people also started sharing their own experiences.
The actor said it is yet to sink in that something she directed, after battling countless doubts, will be out for the world to see.
The 18th edition of the film gala, scheduled from July 21st - 25th, will be held in a virtual format in the wake of the COVID-19 pandemic.
"Human" is produced by the "Delhi Crime" actor's husband, filmmaker Vipul Shah, who also serves as a co-director alongside "Zubaan" helmer Mozez Singh.
During an Instagram Q&A session on Thursday night, the 48-year-old actor was asked by one of her fans to name a movie she rejected that went on to become a hit.
The 'Delhi Crime' actor lauded the film's script, written by Sumit Saxena, Vishal Wagh, Saurabh Bharat along with Kashyap, and said she is excited to be a part of the movie.
The short film has been shortlisted in the finalist category of the Oscar-accredited film festival and will undergo the final round of judging next week.
