How to get a set of edges with attributes starting from a list of nodes in igraph?

I have a large igraph where the vertex of interest were extracted, then out of that subgraph, nodes with the description of interest were extracted. Now I want to extract the edges with attributes corresponding to those nodes with the description of interest.

I tried with edges.table <- E(subgraphGRN)[from(genes$Names)] but I would like to get the attributes as well. Any suggestions?

maybe E(subgraphGRN)[[from(genes$Names)]] with double brackets. Double brackets provides you with all the information of the edge vector.

Also, maybe E(subgraphGRN)[[from(genes$Names)]] %>% subgraph.edges(graph = subgraphGRN, eids = .) %>% as_data_frame() if you want to use the information for non-graph processing.
