version tobiiglassesctrl==2.4.3 does not compile due to opencv-python==4.1.2.30

[HAJEKEL]

When I try to instsall version tobiiglassesctrl==2.4.3, I get the error:
8.137 ERROR: No matching distribution found for opencv-python==4.1.2.30
I have the latest version of pip3.
Also when I install tobiglassesctrl with pip, by default tobiiglassesctrl==2.2.6 gets installed.
I checked that using:
import pkg_resources

version = pkg_resources.get_distribution("tobiiglassesctrl").version
print(version)
