Where can I find dashboard widgets on OS Catalina?

Here's what I'm talking about: I couldn't find it anymore, I used to set it as a hot corner in **System Preferences > Mission Control**, I tried to search the keyword "Dashboard" in System Preferences but ended with no luck. Did Apple remove Dashboard on OS Catalina? If not, where can I find it? Thanks a lot! Edit: Seems like dashboard is removed from OS Catalina (thanks to the comment linking to other similar questions!), **Is there any way to put dashboard widgets on desktop like it's shown in this video ?** UPDATE: **Is there a way to get the Converter Tool somehow?** (the widget that can convert currency, length, pressure, weight all in one!) Recommendation of similar Apps is welcomed too!
