OIDs from net-snmp agentx not showing in smpwalk unless specified explicitly

Question

I've created custom SNMP agent and want it's output to be included in results returned by snmpwalk with no OID specified. OIDs appear when I specify it in the commandline:

$ snmpwalk -v 2c -c public 192.168.0.145 .1.3.6.1.4.1.50536
SNMPv2-SMI::enterprises.50536.1.1.1.1.2.1 = STRING: "foo0"
SNMPv2-SMI::enterprises.50536.1.1.1.1.3.1 = INTEGER: 5030
SNMPv2-SMI::enterprises.50536.1.1.1.1.4.1 = INTEGER: 5030
SNMPv2-SMI::enterprises.50536.1.1.1.1.5.1 = INTEGER: 5030

However, they don't appear when I don't specify my custom OID:

$ snmpwalk -v 2c -c public 192.168.0.145 | grep 50536
$

I have view systemview included .1.3.6.1.4.1.50536 in my snmpd.conf, this does not help

# cat /usr/local/etc/snmpd.conf 
agentAddress udp:161,udp6:161,unix:/var/run/snmpd.sock
sysLocation test
sysContact test
sysDescr Hardware: amd64 Intel(R) Core(TM) i5-4460  CPU @ 3.20GHz running at 3192 Software: FreeBSD 11.0-STABLE (revision 199506)

view   systemview  included   .1.3.6.1.4.1.50536
master agentx

rocommunity "public" default
iquerySecName initial

What else can be causing this problem?

By default, NET-SNMP snmpwalk walks 1.3.6.1.2.1, according to it's man page
