Is it safe to leave a Boox devide plugged in after finishing charging?

Classically, it was considered important not to keep the charger plugged into your phone too long after it was done charging, since the batteries would then heat up and damage the phone. However, modern phones do not have this issue; they stop charging when they reach the full battery level, so no heating is taking place. (And as far as I know, this is not related to fast charging technologies in any way.) Is this also the case with Boox tablets? Can I charge them the whole day without any issues?

This is particularly important for me to know because the HDMI monitor mode on the Max 3 encourages us to plug in the charger because of high power usage.

Yes, we have double checked with our relative colleagues that it is safe to do that.
