I’m new to Filament and I’m having a problem to display a record in filament

this is my table

stations Table
id
station_name

unit_assignment Table
id
station_id
personnel_id

personnel table
id
name

in my UnitAssignment Model

public function station()
{
    return $this->hasOne(Stations::class, 'station_id', 'id');
}

public function personnel()
{
    return $this->belongsTo(Personnel::class, 'personnel_id', 'id');
}

in my Personnel Model

public function unitassignment()
{
    return $this->hasOne(UnitAssignment::class, 'personnel_id', 'id');         
}

in my Station Model

public function unitassignment()
{
    return $this->hasOne(UnitAssignment::class, 'station_id', 'id');         
}

now, I can’t find a solution how to call the station_name field in my PersonnelResource page

TextColumn::make('unitassignment.station_id')->label('Unit Assignment')

This one work but only displays the station_id, i want to display the station_name.
