Unrecognized property 'LabelTextColor' for class 'images.roi.Point'

Hi, on the official website of matlab:

https://uk.mathworks.com/help/images/ref/drawpoint.html#mw_d573bdc7-78b6-41f4-8ee9-c5451e542dc7_sep_mw_2c2e3363-b8ef-4bf5-b93c-7d78a6b714f1

it specifies that the point roi has the property LabelTextColor and LabelAlpha.

However, when I created a roi point as:

p = drawpoint;
p.Label = 'balabala';
p.LabelAlpha = 0;

The compiler complains that this is an unrecognized property.

Is there a way to set the text color and alpha of the label?

Thank you very much.

Which release are you using? The LabelAlpha property does not exist in R2020a, but perhaps it was added in R2020b ?

same here: Unrecognized property 'LabelAlpha' for class 'images.roi.Circle'. Thanks Gouiri C.
