Money Market Funds

Hi, just wondering if anyone can help with this, or raising this as a potential idea if it isn’t available.

Has anyone found any decent money market funds that can be accessed using the Freetrade platform? Something akin to this on vanguard:

I’d really like to have the option of parking money in a money market fund in order to keep a competitive interest rate given how bad banks are at passing cash rates on to savings. It would also mean using the ISA allowance which is a nice benefit and adds flexibility to investing the money later down the line.

Best I have been able to find is £ERNS which seems like a decent option but still looks potentially like a slightly higher risk option to a true money market account.

Thoughts welcome!
