conditional_effects plot for monotonic predictors - lineplot vs catergorial plot

[Famondir]

Hi,
I fitted a model with a model with monotonic predictor:

binomial_base_model_fs_mono <- brm(
  data = success_moduls,
  n_Prüfungsstatus | trials(n_Prüfungen) ~ 1 + mo(Semester),
  family=binomial(link='logit'),
  cores = 4,
  sample_prior = TRUE,
  file = "models/binomial_base_model_fs_mono.rds"
)

When variable Semester is numeric (integers) the conditional_effects plot shows a linegraph what was not expected:

Is there a easy way to get a categorial plot with errorbars like this?:

I had to refit the model and change the variable type to ordered to get this.

I tried to use the categorical, ordinal and re_formula options from conditional_effect but had no luck.
