Should the Mu'adh-dhin turn his mouth (face) and look from side to side during the Adhan?

وَيُذْكَرُ عَنْ بِلاَلٍ أَنَّهُ جَعَلَ إِصْبَعَيْهِ فِي أُذُنَيْهِ. وَكَانَ ابْنُ عُمَرَ لاَ يَجْعَلُ إِصْبَعَيْهِ فِي أُذُنَيْهِ. وَقَالَ إِبْرَاهِيمُ لاَ بَأْسَ أَنْ يُؤَذِّنَ عَلَى غَيْرِ وُضُوءٍ. وَقَالَ عَطَاءٌ الْوُضُوءُ حَقٌّ وَسُنَّةٌ. وَقَالَتْ عَائِشَةُ كَانَ النَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يَذْكُرُ اللَّهَ عَلَى كُلِّ أَحْيَانِهِ.It is said that (during the Adhan) Bilal used to put his (two) fingers in his (two) ears, whereas Ibn 'Umar never put the fingers in his ears. Ibrahim said that there was no harm in pronouncing the Adhan for the Salat (prayer) without ablution. 'Ata' said, "Ablution is essential and it is Sunna (legal way)." 'Aishah رضي الله عنها said, "The Prophet ﷺ used to remember Allah during all times." ​​
