The paperlike is only to give you feel of paper when using the pencil. If you are ok with usual tempered glass, most reasonably priced ones will work. On my 8th gen, I have some tempered glass which I got last year from amazon for Rs. 500 for 2 pieces and I can easily use it for writing using pencil.
Btw, if you are later interested in buying almost brand new apple pencil, do let me know as I am not using at all but making sure it is charged always and it has been used less than 5 hours in total.
