Kee plugin and keepassx

I have windows 10 pro installed on laptop with keepassx 2.0.3
Is this kee plugin also compatible with keepassx
I installed the keepassrpc plugin
I created the folder Plugins in keepass install folder - but below toolsmenu there is no plugins menu to check if plugin keepassrpc is installed/loaded
and looking at the kee icon in firefox it states : you are not login to keepass
any help is welcome
best regards, Guy

Why do you use a security app which is no longer updated since 2016.

migrated to keepassxc (version from 2021)
and installed the rpc to connect firefox to keepassxc - ok
all pw at same location…
