Is there a way to make a data frame out of an RD object?

Question

I am running an RD regression and would like to tidy it up to export its output into an excel. However, when I try to use the tidy() function:

R2to1RDD = rdd::RDestimate(data = filter(group_by(Affinity_County_Weekly.csv, countyfips, WeekAfterReopening2to1 < 5 & WeekAfterReopening2to1 > -5), Reopening2to1), 
                      changeVsLastWeekSpend ~ WeekAfterReopening2to1,
              #  |  factor(winner1001010) + factor(income_quartile),
                cutpoint = 0
                #type = "sharp" 
)
summary(R2to1RDD)
R2to1RDDDF = tidy(R2to1RDD)

Returns an error:

"Error: No tidy method for objects of class RD" is returned.

Here is the data:

 countyfips WeekAfterStimulusPayments changeVsLastWeekSpend
   <fct>                          <dbl> <pseries>

 9 1001                               4  16.9800885          
10 1003                              -4  -7.7897083          

Is there any other way to make a data frame out of an regression object, specifically an RD object?
