Not quite, no. The plugins folder is initially empty. You need to place the plugin file in it yourself.
Sazoji Your instructions are good, but the zip in step 1 is not used until step 4. This is confusing.
I think you should reorder the steps:
1. download latest
You must be registered to see the links
for x64 windows from build links (literally just the latest artifact on the list)
2. run once
3. download zip from
here
4. add plugins
5. keep
Uncensor_for_ricca_net6.dll, remove Texture_Replacer_il2cpp.dll and Uncensor_for_ricca.dll
