Internal job posting in TCS

Hi All, I'm in support project from 2.5 years but I want to switch my domain to Development. I have good knowledge of HTML,CSS, JavaScript and React. Can anyone help me, how to switch my domain in TCS itself so that I get good hands-on experience. It's very difficult to get released from the project but may be after getting selected in the domain, I can ask for project release from the current support project? Anyone any suggestions please and also let me know if anyone have vacancy in their project so that I can join their team? Please help!!
