According to the source, what was Sai Baba's direct role in the creation of the Sai Satcharita?

According to Chapter 2, Sai Baba's role was not merely to grant permission but to be the actual author working through the writer. He explicitly stated, "He is merely a pretext; I myself shall write my own story!" This illustrates that Baba intended to be the true author, using the writer as an instrument. He instructed the author to dissolve his ego and surrender it at His feet, promising full assistance to one who does so. Sai Baba clarified that when the ego is completely gone, He himself would enter with 'I-ness' and write with His own hand, making the human author a pretext for the work.
