MGAB-V240: standstill interrupted by fading (AM CVn?)

Using ZTF data in 2022, I noticed that a standstill was interrupted by up to 2 mag short fading at least four times. The object became brighter (for a short time) after such events. The fading rates exceeded 1 mag/d in some cases and this object may be an AM CVn star. If this identification is correct, repeated regular outbursts before 2020 were superoutbursts (with a supercycle of about 10-15 d). Faint, but unusual object.
