SQL Developer runs the below query (which you can check by clicking the Run Report in SQL Worksheet button) for its session browser:

with vs as (select rownum rnum,
                            inst_id,
                            sid,
                            serial#,
                            status,
                            username,
                            last_call_et,
                            command,
                            machine,
                            osuser,
                            module,
                            action,
                            resource_consumer_group,
                            client_info,
                            client_identifier,
                            type,
                            terminal,
                            sql_id,
                            sql_child_number
                       from gv$session) 
           select vs.inst_id, vs.sid ,serial# serial, vs.sql_id, vs.sql_child_number,
                  vs.username "Username",
                  case when vs.status = 'ACTIVE' 
                            then last_call_et 
                       else null end "Seconds in Wait",
                  (select command_name from v$sqlcommand where command_type = vs.command ) "Command",
                  vs.machine "Machine",
                  vs.osuser "OS User", 
                  lower(vs.status) "Status",
                  vs.module "Module",
                  vs.action "Action",
                  vs.resource_consumer_group,
                  vs.client_info,
                  vs.client_identifier
             from vs 
            where vs.USERNAME is not null
              and nvl(vs.osuser,'x') <> 'SYSTEM'
              and vs.type <> 'BACKGROUND'
              order by 1,2,3

Based on that, grants needed:

grant select on sys.gv_$session to your_user;
grant select on sys.v_$sqlcommand to your_user;

You may need additional privileges for other options.
