Rediscovering Removed Thing

I installed Xiaomi Mi IO Binding. Everything works OK. Recently I bought 3 Yeelight Bulbs added them as a thing with token through PaperUI after they were automatically discovered in inbox. Then I removed them in Configuration>Things in PaperUI. Now I would like to add them again but now I cannot find them via binding Search. I cannot add them manually because I need their tokens.

Question: How to rediscover Thing thing after it was removed?

system info: Openhab2 version 2.5.5-1 on Raspbian on Raspberry Pi 4.

I have already tried: restarting Openhab, Rebooting Rpy, deleting contents of /var/lib/openhab2/cache and /var/lib/openhab2/tmp folders

I found tokens in /var/lib/openhab2/miio/miioTokens-de.json then I added them manually via config files.
