Merge contacts and anonymous

I noticed that when someone leaves their email on the form, the lead is created as a contact who has the IP reference. However, if this lead accesses another page on my domain that has the script registered by the WP Mautic plugin, it does not integrate the history of these accesses in the created contact, creating an anonymous contact. How to make Mautic merge these contacts automatically?

Hi @marcosaanjos_1 , at first perhaps some infos, how Mautic works:

My question would be: is it possible to combine the two contacts (the identified one and the unknown one), if the setting IP anonymize is enabled?
