Set "online" as default?

I use Jitsi Desktop 2.10.5550 as SIP client for phone calls. After PC start / Jitsi start the default status is “absent”, so Jitsi does not react on incoming phone calls. I would like to permanently change the default status (after Jitsi starts) to “online”, but did not find a parameter or option to change the default.
Any help appreciated.
