How to get Subsidy under Sindhu Darshan Yatra in Gujarat?

The Gujarat government will provide financial assistance of Rs 5,000 to every tribal person who undertakes a pilgrimage to Ram Janmabhoomi in Ayodhya. As per the media reports, the tribal people are descendants of Shabari Mata who met Lord Rama during his 14-year exile. I also want to apply under this scheme and avail the benefits of Sindhu Darshan Yatra, can anyone help me how can I get the subsidy under this scheme and what documents are required for this? Thanks
