How we can invest into SME fund

Few days back , I saw SME IPO - Subam Papers Limited and found some fund house already applied for angel investor etc.

One fund house is Resonance Opportunity Fund and their portfolio here https://www.chittorgarh.com/report/ipo-anchor-list-vs-listing-gain/134/45/ .

I have one question. How we can invest into SME fund like Resonance Opportunity Fund ?
and these fund are similar to fund like big companies (SBI, ICICI MF, Franklin, etc) ?

Is public can invest into SME fund ? or they are private ?
