How to add additional IPv4 to VPS?

Question

CentOS

Rented a VPS, installed Centos 8 and ISP Manager.
I ordered an additional IPv4, but they told me to add it somewhere on the server myself so that I could use it. The instructions were given at the link https://contabo.com/blog/configuring-additional-ip...

Help me figure out how to add a new IP?
As I understand it, I need to add some kind of entry to the /etc/sysconfig/network-scripts/ifcfg-eth0 file?
But I can't figure out which one?

Now this file has the following content:

# Generated by parse-kickstart
TYPE=Ethernet
DEVICE=eth0
UUID=22ac4f0f-d703-49d3-9756-494f107dbca4
ONBOOT=yes

NETMASK=255.255.224.0
GATEWAY=62.171.128.1
IPV6INIT=yes

DNS2=213.136.95.11
PROXY_METHOD=none
BROWSER_ONLY=no

DEFROUTE=yes
IPV4_FAILURE_FATAL=no
IPV6_AUTOCONF=no
IPV6_DEFROUTE=yes

IPV6ADDR="2a02:c207:2055:9589:0000:0000:0000:0001/64"
IPV6_DEFAULTGW="fe80::1"
IPV6_DEFAULTDEV="eth0"

Info about the new IP:

109.205.176.239

Please use the following network configuration:
Network:	109.205.176.0
Gateway:	109.205.176.1
Broadcast:	109.205.183.255
Netmask:	255.255.248.0
Prefix:		/21
