Updating/developing plugins no longer possible?

I want to update my plugin but I no longer see developer options for updating/adding new plugins. Is this no longer possible? To my understanding, they will be replaced by GPTs which i think is better but in the meanwhile my plugin has issues and i need to fix it.

It is still possible for me. Go to the standard ChatGPT interface, then go to the Plugins option (below GPT-4 and GPT-3.5). Then to the right of “ChatGPT Plugins” you should have a list of installed plugins in a scrollable window. Go right to the bottom of that for “Plugin Store” where you still have options of “Install an unverified plugin” for example. I’ve recently updated a plugin, and was able to delete and then reinstall it.
