Use of undefined constant FT_UID - assumed 'FT_UID'

[RhRU]

I tried to install https://github.com/Webklex/laravel-imap.
Only on Laragon I get the error
Use of undefined constant FT_UID - assumed 'FT_UID'

This is a PHP constant so it shouldn't pose any problems whatsoever. However I have to go to the plugin and "quote" the constant. Needless to say That is so wrong but just to get everything working.

I have talked to the plugin creator. He said that that error pop's up when imap is not install on the server.
Any thoughts?

@RhRU : Did you enable imap extension? (Menu > PHP > Extension)
