Importing the feature(sequences) to R with qiime2R

Hi everyone!

Im importing my qiime2 artifacts to R wirh qiime2R package. But Im having some trouble importing the sequences. When i try to do so with read_qza command, a large list is generated but I cannot extract a dataframe from the data sublits becase It seems to not be a matrix.

Does anyone has any idea?

Thanks in advance
