Adding Google reviews widget with elfsight

Site URL: https://www.cathartjewellery.com/

Hi,

I have set my business up on 'Google my Business'. I have not listed an address as I work from home and do not have a business address but rather set my location as London.

I would like to add a an Elfsight widget to one of my pages so that it shows my google reviews. But I can't find my business on the Elfsight widget, I assume this is because my business is not listed with an address on Google.

I have attached a screen shot of the Elfsight widget where I am supposed to find my business and cant.

Has anyone had this problem or have a solution?

Thanks,

Cat
