Why Logseq can delete the notes in obsidian?

I just download Logseq and the Logseq scan all my file when I create a new file for Logseq.

And then when I deleted the Logseq file, I though it was just delete the file on Logseq.

But then when I go back to obsidian, the file was gone.

and now I can’t find the file that I deleted in my laptop.

I am using Mac, so if anyone knows how can I find the notes?

many thanks…
