Create a module for the site on the ocStore

Web developer services are required. You need to create a module for the Lightshop template (ocStore 2.3.0.2.3) to display 2 currencies at once. The main currency is Belarusian rubles, it is necessary that when customers come from Russia or other countries (calculation is planned on the basis of the GeoIP PRO module), the cost of goods on the main and other pages is displayed in Russian rubles and their equivalent in Belarusian. I planned to use the module “Currency plus” for this, but it is impossible to configure the display in 2 currencies in the basket, and the author now has no opportunity to do a rework.
