Brms - Variable/Feature Selection with ordinal response

Hi everyone,
I’m a new student that want to approach a bayesian statistics. In my study case I have 56 obs and 46 variables (hhcframe dataset) and after estimate the model with shinkrage approach (set prior lasso and horseshoe) and I can’t continue. I applied “Wald Test” (Estimate/Est.Error) but no variable is higher than |1.96|, then what you suggest to me for variable selection and compare these shinkrage models with frequentis approach?

Thank you so much for attention.

What about these discussions?:
