Monitoring PPP-session, L2tp-session on MikroTik

How to monitor via SNMP ppp sessions of clients, or l2tp sessions. I use Prometheus (snmp_exporter, node_exporter).
I am trying to create a dashboard that will display the client name, ip address, session time, incoming and outgoing traffic in a table.
I don’t understand what metrics to take to build regular expressions in Grafana?
Can someone provide such expressions? Or explain how to build them based on metrics from a ready exporter?
I am ready to provide any information to solve this problem. Thanks in advance.

Good afternoon, I am already using the first dashboard as a base. But I am interested in the possibility to create a column of session duration time, ip-address. I don’t understand which metric from the ‘mikrotik’ block will help me to add this information. How to do this?
