adding a publication with two different dates with harvard style

hello together, I have an issue with adding items. I want that both, the publication date and the date, where the publication was updated show up. but I can't add a second date in the info fields. Does somebody of you know how I can do that?

Here is an example of an item I want to cite:
https://www.ncbi.nlm.nih.gov/books/NBK1384/
when I chose on this page cite this page I get this:
Hunter JE, Berry-Kravis E, Hipp H, et al. FMR1 Disorders. 1998 Jun 16 [Updated 2024 May 16]. In: Adam MP, Feldman J, Mirzaa GM, et al., editors. GeneReviews® [Internet]. Seattle (WA): University of Washington, Seattle; 1993-2025. Available from: https://www.ncbi.nlm.nih.gov/books/NBK1384/

I also want to have it like that, that the first and then the updated date show up. How can I do this?

Many thanks in advance
