Reliance CPSE ETF FFO Investment Proof

I’ve invested in Reliance CPSE ETF FFO. As this ETF is eligible for RGESS 80CCG, How can I get the investment proof.
I contacted zerodha for this and they just showed me in holdings sections under kite and said that is the proof.
I also contacted Reliance Nippon Asset Management and they told me that as the investment is linked with the DP you need to contact the zerodha for this.
How can I get investment statement (not holding statement under kite) for tax submission?

There is a report we can provide you. Send an email to pawan[at] asking for it.
