How to use bionic-updates? [duplicate]

I have a dependency problem on 18.04, libglib2.0-0 is a bit too old (I need 2.56.3 but only 2.56.1-2ubuntu1 is available).

When looking at the details of the package, I see that

Paquet libglib2.0-0
(...)
bionic (18.04LTS) (libs): GLib library of C routines
2.56.2-0ubuntu0.18.04.2 [security]: amd64 i386
2.56.1-2ubuntu1 [ports]: arm64 armhf ppc64el s390x
bionic-updates (libs): GLib library of C routines
2.56.3-0ubuntu0.18.04.1: amd64 arm64 armhf i386 ppc64el s390x
(...)

bionic-updates fits the bill. How can I use it with apt?

I currently have APT sources set by default to

deb bionic main restricted universe multiverse
deb-src bionic main restricted universe multiverse

It was simply a matter of adding bionic-updates to the sources list:

deb bionic main restricted universe multiverse
deb-src bionic main restricted universe multiverse
deb bionic-updates main restricted universe multiverse
deb-src bionic-updates main restricted universe multiverse
