Plexamp on macos: code signature issue?

I’ve been using plex, but for music would like to try out the plexamp app on macos.
For security reasons, I checked the code signature, but it seems that the plexamp app on macos has a different codesign team/company id than the main plex app or the ipad plexamp ruunning on apple silicon macs?

codesign of plex.app, or the plexamp app downloaded from appstore (which is the ios app running on apple silicon mac): has

Authority=Developer ID Application: Plex Inc. (K4QJ56KR4A)
TeamIdentifier=K4QJ56KR4A

but the macos plexamp app downloaded from plex.tv appears to have a different idenitfier/company name?

Authority=Developer ID Application: Plex, Inc (399DR5LB2A)
TeamIdentifier=399DR5LB2A

is it the legit app/why the different TeamIdentifier/Authority names?

whole codesign output:
