Thanks for the reply.
This demo https://xstore.8theme.com/elementor/demos/niche-market04/ventors-list/ uses “Multivendor Marketplace Solution for WooCommerce – WC Marketplace” plugin, but on your site, this plugin is not activated, so you can see just a shortcode https://prnt.sc/nfGmsgj45_M3 To install and activate the plugin, go to XStore > Plugins Installer https://prnt.sc/GwpjB7BxISht
You need to select between WCMP and Dokan plugins.
https://prnt.sc/a2SIfrY1qPXz – it is ok for the Dokan plugin, here is the demo example https://xstore.8theme.com/demos/2/dokan/store-listing/
More info you can find in docs of mentioned plugins.
Let us know if any further assistance will be needed
