As mentioned in a comment, retirement plans often use "classes" of a fund that are not publicly traded, so they don't show up on finance sites.
You could use a different class of the same fund as a proxy (the provider's website should give you tickers for each class) but you'd want to look at the returns to make sure they are compatible. The price may be different so compare the relative changes in price.
That said, when I googled the exact name of the fund I got a hit from Yahoo Finance under ticker 0P0000XVTL.BO. That ticker may be "hidden" from the search function within Yahoo though, so you may not be able to add it to your "portfolio".
