In GoldenChaos, AirPods button does not connect AirPods Pro anymore (in Big Sur)

MacBook Pro 15" on Big Sur 11.0.1. Using BTT version 3.505 (1643).
Since updating to Big Sur, pressing the AirPods bottom on the TouchBar does not toggle connection. It does nothing. My AirPods are called Martin's AirPods Pro. Is there something I must do or is this a known problem?
