After whom/which ethnicity was the termine ‘Lekianoba’ named? Etymology of the word Lekianoba (Georgian: ლეკიანობა)

Hello, fellow Georgians,

A question related to the 15-18 century’s history.

There is a discuss in Dagestan about who were called ‘Leks’ by Georgians, and of which word it had derived from? (The word ‘Lek’/’Lekianoba’ )

is it (Leki/Lekianoba) From the name of Dagestani Salmon(Lak people) or the Dagestani Lezgins? Or maybe the Avars? (Why then LEKI-anoba?)

( p.s., modern ‘Lezgins’ of Dagestan were called ‘Kuriners’/Kurawi until the 1920s, and the republic of Dagestan was named ‘Lesghistan’/Lezgistan back then (not ‘Dagestan’, modern name), but the name Lesghistan had same meaning as Dagestan back then, it was multinational/multiethnic name, not of a certain ethnicity of Dagestan. Something like ‘Belgium’, while there is no one and alone Belgian ethnicity or ‘Belgian Language’, but a few of them. )

So, who were those ‘Lekians’ and their kings, maybe names of them?

https://en.wikipedia.org/wiki/Lekianoba

How can we find that out? Maybe there are still some historical notes about those ‘Leks’ and their kings/Khans? Where is that historical information now?

Many thanks//
