Where are OpenVPN connection logs stored in Android?

Question

Android

The android emulator (LDMultiPlayer4) has the OpenVPN for Android app installed. The config, like the application itself, is installed into it via dn adb.
Question: on what path in the system can I find the log of its connection to the VPN? Or how can you enable logging with saving to a specific path, if it is disabled by default?

If you install some program, for example, Termux, then you can click on the "Send log" button in the log window and select Termux, then the log file will be saved in the Termux system folder. But I would like to do it with a script.
