How to change corresponding author of my published papers?
I do not know whether it is possible to change the corresponding author, but I suspect it is not something journals do as they are reluctant to change published articles.

To reduce the issue, however, you could improve the online profile of the article:


Have a Google Scholar profile, so someone interested in the article has a link to your profile
Similarly, you could have a Research Gate profile and an Orcid number
Have a professional website


In this context, someone with a question about the article can easily find you, if they do not receive an answer from the corresponding author. Yes, it is less direct than corresponding author, but I think it is the best you can do.
