DSP Credit Risk Fund listed on approved securities but not on coin app

I’m not able to access DSP Credit Risk Fund via Coin Mobile/Desktop search but it is listed on
Approved list of Securities at Zerodha spreadsheet under non-cash component.

I’m planning to invest in this fund via Zerodha account.

How can I do that?

DSP Mutual Fund stopped fresh investments in this fund in December 2021. Hence it is not available on Coin. Announcement from AMC can be checked here.
