Short summary of your issue

When using the @readonly tag on for instance a type, it isn't showing up in the docs. With this the doc is missing crucial information for the user to use a lib. Could you please consider supporting this jsDoc tag ( https://jsdoc.app/tags-readonly.html )? It's pretty useful and has a lot of benefits for better docs!

Something like this would be nice to see in the docs (see lock symbol to indicate readonly):
