Odoo | POS | Customization

I have this addon purchased from the odoo app store to scan lots in the POS https://apps.odoo.com/apps/modules/13.0/pos_product_by_lot_number/#attr= and I need to be able to scan a lot code and when it is recognized in the selection wizard show all the available locations and in which packages they are (i am using packages like pallets that contain lots codes of products). From that wizard I want to choose where to serve the material from, as I am doing now from the backend with this module https://github.com/OCA/stock-logistics-warehouse/tree/13.0/stock_quant_manual_assign.
