Android 12 VPN options limited

After updating to Android 12 Beta 2, I only see 3 types of VPN connections possible (Network/Internet->VPN->+): IKEv2/IPsec MSCHAPv2/PSK/RSA. Before I used to connect to my L2TP/IPsec PSK (pre-shared key), but now that option seems missing. I’ve tried IKEv2/IPsec PSK option, but the save button is grayed out without adding something called ‘IPsec Identifier’ which I don’t have, and it’s likely a wrong protocol anyway.

Any info on if Google plan to restore L2TP/IPsec PSK option? Or maybe some recommendation for a third party VPN client which supports it?
