Maybe you could use ibus? See 
https://unix.stackexchange.com/questions/689826/input-methods-for-anceint-greek-and-other-diacritic-heavy-languages

Also, I don't know Greek, but using ibus you can also insert any UNICODE 
characters with the keyboard shortcut Ctrl+Shift+U. For example, to 
insert ᾇ (Greek small letter alpha with dasia and perispomeni and 
ipogegrammeni, whose UNICODE is 1F87):

 1. Ctrl+Shift+U
 2. 1F87
 3. Enter

Finally, even though you're not using GNOME, you could install the GNOME 
Characters app 
(https://packages.guix.gnu.org/packages/gnome-characters/), which I 
allows you to search and copy any UNICODE character.

Hope that helps.
