Removing Filter on Out of the Box Detail "Opportunity Team" in Opportunity Section

Hello,

We are using an out-of-the-box detail created by Creatio with code "OpportunityTeam" in the Opportunity section and would like to remove a filter on it.   The Contact lookup on the detail object "Opportunity participant" is being filtered by the Account lookup on the Opportunity object.  This means that users can only add contacts to the "OpportunityTeam" detail which have the same account as the account listed on the opportunity.  We do not want this behaviour so are looking for how to remove it.

There are no business rules on the Opportunity section page or the detail causing this filter.  Does anyone know which schema or perhaps mixin is causing this filter?



Thank you for your help!
