I've lost my buds 2/ Does buds pro 3 can be found by "samsung find" while in case?

Hello, Long ago like 2 weeks ago I've lost somewhere my buds 2. I tried to find them by using "samsung find" but they don't respond :c Is this because of the fact I've lost them while they were in my case and this function only works while bud is outside of it? Why I cannot detect them :/

Also I say goodbye to them and I'm thinking about buying galaxy buds pro 3, I've read that they can be found even in case and the case lights up while searching for. Is this true?
