if-statement: How to delete outliers from a nested dataset when they are truly extreme via an iterative method or pipe operator

I'm trying removing outliers from this nested dataset

df_join
# A tibble: 12 x 2
# Groups:   signals [12]
   signals     data             
   <chr>       <list>           
 1 P3FCz       <tibble [75 x 5]>
 2 P3Cz        <tibble [75 x 5]>
 3 P3Pz        <tibble [75 x 5]>
 4 LPPearlyFCz <tibble [75 x 5]>
 5 LPPearlyCz  <tibble [75 x 5]>
 6 LPPearlyPz  <tibble [75 x 5]>
 7 LPP1FCz     <tibble [75 x 5]>
 8 LPP1Cz      <tibble [75 x 5]>
 9 LPP1Pz      <tibble [75 x 5]>
10 LPP2FCz     <tibble [75 x 5]>
11 LPP2Cz      <tibble [75 x 5]>
12 LPP2Pz      <tibble [75 x 5]>

where the entire content of it is the following one:

I've tried to check for the presence of outliers as follows:

outliers_table <- df_join %>%
  unnest() %>% 
  dplyr::select(COND, signals, value) %>% 
  group_by(COND) %>%  #it is the equivalent to use as grouping variable the time
  identify_outliers(value)

That turns That turns

A tibble: 30 x 5
   COND    signals     value is.outlier is.extreme
   <fct>   <chr>       <dbl> <lgl>      <lgl>     
 1 NEG-CTR P3FCz       -11.6 TRUE       FALSE     
 2 NEG-CTR P3Cz         13.7 TRUE       FALSE     
 3 NEG-CTR P3Pz         15.1 TRUE       FALSE     
 4 NEG-CTR P3Pz         13.7 TRUE       FALSE     
 5 NEG-CTR P3Pz         23.4 TRUE       TRUE      
 6 NEG-CTR P3Pz         15.8 TRUE       FALSE     
 7 NEG-CTR P3Pz         14.4 TRUE       FALSE     
 8 NEG-CTR LPPearlyFCz -11.8 TRUE       FALSE     
 9 NEG-CTR LPPearlyCz   17.2 TRUE       FALSE     
10 NEG-CTR LPPearlyPz   25.6 TRUE       TRUE

If I'm interested in delete all of those values that are TRULY EXTREME, how could do I do by using some iterative function orr some if statment?? Please just consider also other alternative in case it is easier (also to keep on the command I've written by adding another %>% command row) that scripring down a for loop or some other function.

Thanks in advance
