You may add that element with correct settings in that plugin -> https://prnt.sc/0pzqVdsQJbTA -> https://prnt.sc/L3OlTtCm9wtp
Also, you may remove the XStore Cart element as was described before -> https://www.8theme.com/topic/remove-single-store-page-swatches-order-pay-on-mini-cart/#post-324731
As we see that free version of that plugin is a bit limited but maybe still ok for your purposes. Otherwise, you will find the pro version of it or check and look for another free plugin for these purposes.
