Need help with a wireless access point recommendation

I think I’ve found one but I’m not sure if I even know what I’m looking at https://www.amazon.ca/dp/B07FXJHXP4/ref=cm_sw_r_cp_api_i_GSByDbCH7BHBP

This I what I found and if I’m reading correctly I should be able to set it up as a WAP by connecting an Ethernet cord to it in the wan port, but then also be able to connect a computer to it with an Ethernet cord into the lan port. I’m just not sure if I’m even understanding the product correctly and would greatly appreciate some help
