Call Pickup/Group Call Pickup for Extensiones SCCP

Hello everyone, I’m having trouble assigning Call Pickup/Group Call Pickup to SCCP extensions.
I cannot assign the extensions to their respective capture groups, there is some other way to do it apart from the web, it is on the web where I do not see the option to assign the capture group.

Free PBX 16
Skinny Client Control Protocol (SCCP). Version: development 4.3.5 - 90dc24f
Thank you!!
