Wrap the binaries in firejail and place them in the global path.
</para>
<para>
You will get file collisions if you put the actual application binary in
the global environment (such as by adding the application package to
<code>environment.systemPackages</code>), and applications started via
.desktop files are not wrapped if they specify the absolute path to the
binary.
