Permission doesn't work

I added an "admin" permission to a user.
However,

await getPermissions()

await getPermissions()

await getPermissions()

await getPermissions() returns no permissions:

{ permissions: [], orgCode: 'org_bcddc426a6d' }

{ permissions: [], orgCode: 'org_bcddc426a6d' }

{ permissions: [], orgCode: 'org_bcddc426a6d' }

{ permissions: [], orgCode: 'org_bcddc426a6d' }
And,

await getPermission()

await getPermission()

await getPermission()

await getPermission() returns not granted:

{ orgCode: 'org_bcddc426a6d', isGranted: false }

{ orgCode: 'org_bcddc426a6d', isGranted: false }

{ orgCode: 'org_bcddc426a6d', isGranted: false }

{ orgCode: 'org_bcddc426a6d', isGranted: false }
What am I missing?
