Question about Lenovo Yoga Duet 7i

I use a Bamboo Ink and have ordered a very small USB-C male to male from Aliexpress to go with it. That way I can pin the pen to the tablet and always charge it.

I use the Lenovo Active Pen 2 and it works well.

The Lenovo E-Color Pen also fits.

We ordered this one - but the handling is not so good, because it always has to be taken along separately...
