Filament Multiple Many to Many Relation Resource Management

Hello,

I have been working on a school management project. My models are Semester, Classroom & Student. Each semester can have multiple class and each class can be open for teaching for any semester. Since it is one-level-deep many-to-many relation, I have managed to complete this filament relation. However, every classroom has also many student. I first create semester then attach some classes but I also want to attach student to this classroom that is attached to the semester. This phase is what i have problem creating. I thought about multi-tenancy but my requirements is not meet for it.

I am open to any suggestion to improve myself in this topic. Thank you in advance. If you have any question about any clarity, feel free to ask.

My tables are;

Schema::create('semesters', function (Blueprint $table) {
            $table->id();
            $table->string('name');
            $table->timestamp('start_date');
            $table->timestamp('end_date');
            $table->timestamps();
            $table->softDeletes();
});	

Schema::create('classrooms', function (Blueprint $table) {
            $table->id();

            $table->string('city');
            $table->string('district');
            $table->string('education_type')->default(EducationType::FULL_TIME);
            $table->timestamps();
            $table->softDeletes();
});

Schema::create('classroom_student', function (Blueprint $table) {
            $table->id();
            $table->foreignId('classroom_id')->constrained()->cascadeOnDelete();
            $table->foreignId('student_id')->constrained()->cascadeOnDelete();
            $table->timestamps();
});

My models are

Semester.php

public function classrooms()
    {
        return $this->belongsToMany(Classroom::class)->withTimestamps();
    }

Classroom.php

public function semesters()
    {
        return $this->belongsToMany(Semester::class)->withTimestamps();
    }

    public function students()
    {
        return $this->belongsToMany(Student::class)->withTimestamps();
    }

Student.php

public function classrooms()
    {
        return $this->belongsToMany(Classroom::class)->withTimestamps();
    }
