Some users from Adalo database not available via API request

I have released my PWA to big audience and get a problem.
My application logic needs to get adalo users via API request and the filter it by email. I find some users from Adalo users database manualy. But these users which I can find manually is not in API request I’ve got.

And for these users my logic doesn’t work, because i didn’t get Adalo users ids
