hello.
i am using argento 2 Force . i need to add SKU#: before product sku that is showing on top of product title .
I looked into force theme structure and other theme structure to find where this will be placed but could not find any info .
any suggestion where to look .
Thanks.

this is was fixed by editing catalog_product_view.xml .
argument for sku was set to none , replaced with sku and it is showing .

also . since argento templates are installed in vendor folder . do i need to create override before modification to template core ?
