How to increase popup size in the R Leaflet library as per the count?

Question

This is the dataframe named 'sellers_state_name_df' -> Dataframe

What I want is to increase the popup size of the circles as per the 'Freq'. For e.g Acre (1) circle should be smaller in size than let's say Bahia (19).

Here's the code snippet, which I used -> Code Snippet of Leaflet

And the map that is generated -> Generated Map using Leaflet. If there is any solution or any alternative library (R), please let me know. Thanks!

I am expecting getting the popup size with respect to the 'Freq'.
