Comparing coefficients from svyglm using different surveys

Hello,
I'm having some trouble specifying a regression using svyglm. Here's my current code:

dis<- subset(svydesign(
id = ~congl, 
strata = ~strata,
check.strata = TRUE,
weights = ~fact, data = base_2022), bin == 1)
options(survey.lonely.psu="remove")

model_gamma <- svyglm(
       income~ educ+task,design = dis, 
       family = Gamma(link = "log"))

summary(model_gamma)

My goal is to contrast the evolution of a specific coefficient over time. I have ten years of data from the same survey, so the complex survey design essentially remains consistent, with only the data=base_year parameter changing.

What technique should I use to evaluate the change in this coefficient over the years? I'm aware that handling standard errors with survey data can be challenging.

Thanks for your time and interest.
Have a nice week.
