Missing Plugins

Hello,

I am experiencing some problems when installing AFNI, more specifically with the plugins feature.
First of all is worth to mention that, the software is installed and it is working properly however, there is not present any of the plugins that should be installed.
I tried various AFNI versions, with different compilations flags, but none of them have installed the plugins. I perform installations both "by hand" and also using an installation framework such as easybuild.
I also mention that I add the required plugin flags into the .afnirc file.
When running afni it displays the following message:

Path(s) to be searched for plugins:
/scratch/iortiz/software/afni/afni/install/bin

Plugins = 0 libraries read

There is also not present the Plugin box inside "Define Datamode".

Which flags should be used in the installation to enable this feature or install the plugins ??

I am working in a Rocky8.7.

What I am missing ?? Are the plugins installed apart ?? There are little information about this in the documentation about their usage and installation.
