ZZZ -- Departing XXL on the ZZZZZ departure; we noticed the aircraft not turning right after crossing ZZZZZ1. I intervened to start the turn. At that time; ATC cleared us direct ZZZZZ2. The rest of the SID was flown normally. We talked about this later; and we determined that the airplane was still in RWY Track and had not switched to Managed Nav. I was too slow recognizing that the aircraft wasn't turning. ZZZZZ1 waypoint is an overfly point and I should have been monitoring it closer. I also didn't notice that Managed Nav was not armed. Another contributing factor was that due to the current situation; I haven't flown very much in 2020. I definitely felt rusty. No excuse though. Just part of it.
Pilot reported experiencing a track heading deviation and cited rustiness and lack of flying as a contributing factor.
