Question about Lenovo IdeaPad Flex 5

I first bought the Lenovo Active Pen 2, which has the advantage that it has 3 buttons and is easily adjustable on the computer, but the battery compartment quickly broke.
I bought the Precision Pen 2, which is comfortable to hold and rechargeable.

Lenovo Precision Pen 2

I haven't found any pens from other manufacturers that would work.

No, there is no pen supplied with the PC
