This is an optical reconnaissance satellite (or maybe dual-use, I don't know).  There is likely a minimum of open information due to Israeli national security concerns.

EROS C1 and C2 are already on orbit.  We don't know what satellites they are or who partnered with the Israeli national security establishment.

The first step in this plan is the reuse of two operational satellites – designated by Imagesat as EROS C1 and C[2]. These satellites are believed to be two Israeli-operated satellites, providing imaging over areas of interest for the primary Israeli operator.

The most likely candidates for EROS C1 and EROS C2 are Ofeq 16 and Ofeq 11 respectively, but official confirmation on this is lacking.

I do wonder if we can confirm it, e.g. by checking if either of them pass over Eastern China on favorable lighting conditions on October 19:
