Salesforce plugin add Leads in Salesforce but not the Contacts

Your software
My Mautic version is: 3.3.2
My PHP version is: 7.4
My Database type and version is: Mariadb 15.1

Your problem
My problem is:

I installed Salesforce plugin for integration with Salesforce, I have configured all the settings correctly, so i mapped required fields for either Leads and Contacts, enabled option “Push contacts and/or companies to this integration” and “Triggered action push contacts to integration”.

I disabled “Pull contacts and/or companies from integration” becouse i want integration of Mautic to Salesforce and not the opposite.

My problem is that when i submit a form, or trigger a campaign with Salesforce integration, only Leads are created on Salesforce ( I used a Salesforce Sandbox), but i need to create Salesforce Contacts.

So plugin seems to work for leads, but no Contacts are created in Salesforce.

In Contacts Mapping i configured required fields Email and Last Name with the correct pick direction.

Can anyone help me?

Can anyone help me?

Is there the possibility to create Contacts (NOT leads) on Salesforce through the plugin integration?
