Buying replacement chain for City bike

[Handlebars]

I have the SparkBike City, which looks about the same as the RizeBike City. The printing says "KMC" on most links, and "Z' on some links with the word "NARROW" printed around the end curve of some links.
On the KMC site I don't see any chain that has those markings.
Have any suggestions on which chain to buy and/or where to buy?
Thanks!

I've mailed Rize for help, so I'll post the reply I get.

Rize said any ordinary bike chain will be OK. However, I think a chain that isn't narrow may not work well..
I think these chains will do.

KMC Z7 6/7/8-Speed 116L Shimano HG Bicycle Chain​

Chain 7SP KMC Z7, Dark Silver/Brown​

This is the chain I bought https://www.amazon.ca/gp/product/B003AFOV84/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1
It fits without any changes, same number of links as the old chain.

I bought this cheap chain splitter tool, it worked perfectly. https://www.amazon.ca/gp/product/B07TZ7DL67/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1
The pliers were not needed yet because the old chain needed to have the rivet removed and tightening up the joining link on the new chain is automatic. The pliers do work though.
Smooth transmission now.
