Was Olivera Despina daughter of King Lazar of Serbia married to Bayezid 1 eventually captured by Timor Lame ?

What happen to her after that? I am trying to find some reference material. When and how did she die ?Was Olivera Despina daughter of King Lazar of Serbia married to Bayezid 1 eventually captured by Timor Lame ?
Princess Olivera Despina's arranged marriage was Serbia's strategy for survival. Shortly after the Battle of Kosovo, Hungary invaded Serbia, so Serbia reached out to the Turks, its enemy until only shortly before. Most of all, the sultan of the Turks loved the Serbian princess dearly. The argument that Timur harassed the princess is in doubt, too. The sad story of the princess is a tale that has been passed down by Serbians from generation to generation. Historical records in the Islamic world testify to the contrary. There are records that Timur treated the prisoners of war, the sultan and the princess, very well and that Timur became very sad when the sultan died. Princess Olivera Despina lived a long life and died at 72. There are many suspect parts in the Serbian version of the story.
