How to solve unused argument error as part of a meltAssay?

When using meltAssay to convert a SummarizedExperiment object, the central data infrastructure for microbiome analysis in Bioconductor, into long data.frame, I use the following lines according to the instructions in the book:

tse <- transformSamples(tse, method="relabundance")

molten_tse <- meltAssay(tse,
                        add_row_data = TRUE,
                        add_col_data = TRUE,
                        assay_name = "relabundance")
molten_tse

However, I get the following error:

Error in .melt_assay(x, abund_values, feature_name, sample_name, ...) : unused argument (assay_name = "relabundance")

Use the following syntax instead: (abund_values instead of assay_names. There seems to be an error in the book)

molten_tse <- meltAssay(tse,
                        add_row_data = TRUE,
                        add_col_data = TRUE,
                        abund_values  = "relabundance")
