We are getting empty orders from the web store by the name of 'Public user' everytime a user opens the shopping cart but then abandons during the process. Now our reports show many  misleading 'quotations'. How can I automate it so that once every day or hour, Odoo deletes these records from the 'sale.order' model in the Sales and Website apps?

I'm in Odoo v15 Enterprise.

By the way, this https://www.odoo.com/es_ES/forum/ayuda-1/how-to-hide-the-ecommerce-shop-to-unregistered-users-51077?forum=forum.forum%281%2C%29&question=forum.post%2851077%2C%29 is not the solution I'm looking for. We still want for unregistered users to be able to enter the shop and shopping process. We don't want to change that.
