Data assimilation inside the CROCO domain

These is very little information about data assimilation in CROCO. I know that boundary nudging can be applied but what is the status with data assimilation inside the simulation domain?
In one of our projects we would like to use data inside the domain from buoys, floats (e.g. u, v, t, s, sst and bio_tracers).

I found a some information on this forum post 2 years ago. I am wondering if some progress has been made in the latest release (or planned in the near future):

But what tools we have to create these inputs inside the domain? It would be nice to have a test case for this.

I see that @pmarchesiello is involved in this ongoing project for CROCO-3DVAR with demo application in the Mediterranean sea. The aim was to have a system up and running during 2023 - 2024. Any update on the progress on this work? There are python tools mentioned that have been developed for this project.

Question for interior nudging:
If we #define ROBUST_DIAG, which will nudge to what is put in tclm and sclm arrays.

How do we specify tclm, sclm arrays for the interior? I know that when we use make_clim values are created for the whole domain but only the 10 values close to the boundary are used. If for example I have two buoys inside the domain with T,S how do I add them in the tclim and force interior nudging?
