When setting up initially, HOW to tell it ONLy to export 3 products

HI

I have successfully setup your plugin & link to Woocommerce & Facebook for another client on another ticket (about 20 products) with not much issues. All is good.

I have another client who I need to do the same setup and linking with Wooocommerce and Business Facebook & Instagram.

My question is for this client, is they have at least 50 products, BUT I only need to start off with 3 products to be exported ONLY for now.

Therefore when I set up the last client, and linked it all with your plugin, I can’t remember that there was an OPTION or SETTING to choose ONLY certain products to Export to the Business Facebook SHOP on the initial setup. It just exported it all in one go.

How can I achieve just to link the 3 products initially for my other client please ?
I don’t want it auto exporting and adding all products from the Woocommerce products into the Business Facebook.

Thanks
Kristin
