How to use estimation outputs using functions from library `fixest` in `texreg`

Question

I am using the estimation function femlm from the library fixest and want to use the results/values in texreg to create LaTeX tables side-by-side with results from using other estimation functions.

I have been able to include results/values from lm_robust in the library estimatr using

setMethod("extract", signature = className("lm_robust", "estimatr"), definition = extract.lm_robust)

but I have not found a way to do the same with results/values from the library fixest

Any suggestion?

If the only way to do that is to write an extraction function, any tip here would also be much appreciated.

A note on femlm in this regard: it seems that femlm does not support "deviance" (in contrast to other fixest functions). Setting "include.deviance = FALSE" has solved the problem for me.
