How to use the Expression (Affymetrix arrays) file, such as the “GPL570_expression.h5” file？

I see that ARCHS4 provides both RNA-seq (human_tpm_v2.latest.h5) and microarray (GPL570_expression.h5) data files. The archs4r package works well for RNA-seq files. Are there methods or plans to add support for the microarray expression files (like GPL570_expression.h5)? I couldn‘t find related functions in the help documentation.
