Tidymodels stacks - save models after running to reload for use in stacks

I have a technical question. How to I save models from individual experiments to be able to load back into R to use with stacks in a fresh session?

I know I need the predictions from the grid search, I can recreate the resampling with the same seed?

Rds? Something more complicated?

I don't see the documentation, but I might be missing it.

Thanks!!!
