Logical backups in multinode architecture self hosted

Hi
Where I can find proper procedure of backuping multinode timescaledb?

According from here Timescale Documentation | Logical backups with pg_dump and pg_restore I created bash script for ubuntu platform for this. Generally it execute pg_dump on all nodes in screenmode from access node and I needed additional efforts to work with this solution, unix user, pub key and sudoers but is pointless right now. I am wondering it is accepted method. Maybe someone have own script, solution or article to share ?
