Maybe this one? :) Adonit Pro 4

The Stylus Pen for () from Lenovo is compatible with Lenovo devices that already come with a stylus. However, according to official specifications, the Lenovo ThinkPad T14 Gen 4 does not support an active pen if it has not been specially configured with a pen. This means that the pen will not automatically work with the ThinkPad T14 Gen 4 if your model does not have pen support. For the Lenovo ThinkPad T14 Gen 4, there is no general support for the Lenovo Stylus Pen, unless the device was explicitly shipped with pen function. If your laptop does not have pen support, the pen will not work. In this case, only a universal capacitive stylus (without active pen functions) would be an option. To summarise: The pen you purchased will only fit if your ThinkPad T14 Gen 4 model is equipped with pen support. Otherwise, the pen is not compatible. Please check if your model was delivered with a pen to be sure.
