Describe the bug
A description of what the bug is.

To Reproduce
Steps to reproduce the behaviour:

1. I have fitted an Intercept-only model with unqual variance within brms. Student-t family for the outcome. sample_prior = TRUE
bform <- bf(delta_DOC ~ 0 + Intercept, sigma ~ 0 + Intercept + water_volume_z, nu = 3 ) + student()
2. having the brmsfit object I have tried to use the bayestestR::sensitivity_to_prior(b1)
3. Error: Models of class 'brmsfit' are not yet supported.

Specifiations (please complete the following information):

• bayestestR Package Version 0.14.0.2
• brms Package Version 2.21.6
• R version 4.4.1
