Question How to change the TextMesh component inside various buttons throught a script?

sorry for my english

i'm new to unity and i dont know what i'm doing wrong:

i'm making a turn based game and i'm stuck loading the "fighter" move names(in my case mecha)
into the buttons of the hud


public void SetMoveNames(List<Button> moveButtons, List<Move> moves)
{

for (int i = 0; i < moveButtons.Count; i++)
{
if (i < moves.Count)
{
string moveName = moves.Base.Name;
moveButtons.GetComponentInChildren<TextMeshProUGUI>().text = moveName;
}
else
{
moveButtons.GetComponentInChildren<TextMeshProUGUI>().text = "-";
}

}

}

this is the function inside my BattleDialogBox script that i use to update the button's text (that dont work lol)

moveButtons is a list where i've dragged and dropped the textmesh component of the buttons into the exposed fields (like this "[SerializeField] private List<Button> moveButtons;" )

and in my BattleSystem script ;



public IEnumerator SetupBattle()
{
playerUnit.Setup();
playerHud.SetData(playerUnit.Mecha);

enemyUnit.Setup();
enemyHud.SetData(enemyUnit.Mecha);

dialogBox.SetMoveNames(dialogBox.GetMoveButtons(), playerUnit.Mecha.Moves);
yield return dialogBox.TypeDialog("The players take their positions as the match gets started.");
yield return new WaitForSeconds(1f);

PlayerAction();
}

i update the buttons text with this line "dialogBox.SetMoveNames(dialogBox.GetMoveButtons(), playerUnit.Mecha.Moves);"

what am i doing wrong ?
