Private pension insurance still makes sense?

Hi, I have been running a private pension insurance since the beginning of 2024 and pay in €50 a month. Currently this is: Balance: €1619 and the surrender value is €1254. Composed of sp500 terrasissi and I think an msci world. I don't have access right now because the system is being rebuilt... My question now is, should I stop it or let it continue? I'm still under 25 and may/can invest elsewhere for a long time. Especially since the retirement savings account is coming next year,
