The pseudopotential problem of heavy elements

Dear developer,
I need to use sapt to calculate some heavy elements, such as Cd, Se, Mo, etc.It is not specified in the manual how to use the ECP group.How do I call it?It is known that the def2 series base sets has the pseudopotential of the base set after the fourth period. Can I use the def2 series base group to calculate?

                                                 looking forward your reply
