I've been having this issue where I created a LWC to act as an action, and while it shows up fine on the record page, I'm having some issues having it show up on my Community App. At first I thought it was something to do with my meta-data, but I went through and added it, but it doesn't seem to have helped - I'm not exactly sure what I'm missing.
Here's my meta
