Independent Abkhazia

With a POD after the establishment of the Soviet Union, what would be needed for Abkhazia to become an independent state recognized by Georgia and the majority of the world's countries?
 
Someone else as Stalin succeeds Lenin and this successor decide create Soviet Republic of Abkhazia and after collapse of USSR Abkhazia gains independence. Or then worse Georgian Civil War in early 1990's and Georgia is enforced recognise Abkhazia.
