How to remove a network-object host from ASA using CSM flex config

[av]

I have a flex config with something like this.

object-group network OnlyYou_Test
network-object host 1.1.1.1
network-object host 5.5.5.5

Now I want to add
network-object host 2.2.2.2
to the OnlyYou_Test group

and remove network-object host 1.1.1.1
without removing the entire group

What would my new (modified) flex config look like to be able to deploy this to my firewall?

(End result to be
object-group network OnlyYou_Test --> contains only -->
network-object host 2.2.2.2 and network-object host 5.5.5.5 and the host 1.1.1.1 is gone both from the group and the firewall)

Thanks :-)
