Call to undefined method using Relation Manager Attach
@pboivin You're right, it turns out I did need the inverse relationship. In Exercise.php model I added: 
public function exercisesRelatedTo(): BelongsToMany
    {
        return $this->belongsToMany(Exercise::class, 'related_exercises', 'related_exercise_id', 'exercise_id');
    }
public function exercisesRelatedTo(): BelongsToMany
    {
        return $this->belongsToMany(Exercise::class, 'related_exercises', 'related_exercise_id', 'exercise_id');
    }
And in RelatedExercisesRelationManager.php I added 
public function table(Table $table): Table
    {
        return $table
            ...
            ->inverseRelationship('exercisesRelatedTo');
    }
public function table(Table $table): Table
    {
        return $table
            ...
            ->inverseRelationship('exercisesRelatedTo');
    }
I'm not entirely sure why this is needed, but it works! I can now search and attach in the modal as expected. Thank you for your help.
