Hey there Soho,
Yes, that ZIF connector is definitly missing, and will need to be replaced. Their are replacement ZIF connectors that you can get on sites like [link|https://www.ebay.com/itm/234285010784|eBay], or you can try to salvage one from a damaged motherboard of the same model.
As for the process of replacing the connector, it is a bit of a more advanced soldering technique, but should be doable. I'll link a video to the [link|https://www.youtube.com/watch?v=cHKwLPxd5D4|process here] that way you can get a feel for it.
Best of luck to you
