Question Can I remove the numbers at the end of a player name?

Hey everyone this is my first thread here and i'm a beginner so apologies if I don't make sense somewhere in this thread!

I've been trying to implement the leaderboard in my first game for the past week and I found out today that upon submitting/posting a score entry to the leaderboard, you can allow the player to set their own player name when submitting a score, an example would be something like this:
[SerializeField]
private TMPro.TMP_InputField nameInput;

public async void PostScore(ScoreType type, float score)
{
if (score <= 0) return;
try
{
await LeaderboardsService.Instance.AddPlayerScoreAsync(type.ToString(), score);
await AuthenticationService.Instance.UpdatePlayerNameAsync(nameInput.text);

Debug.Log($"Score Posted To Leaderboard - {type}. Score: {score}");

}
catch (System.Exception e)
{
Debug.LogException(e);
await Task.Delay(2500);
PostScore(type, score);
}
}

But when I fetch the leaderboard entries on my leaderboard, whatever I put in the inputfield, for example "TestPlayer", it shows TestPlayer#4382. I'm just wondering if it's possible to remove the digits at the end?

 

I remove the last digits this way:

Code (CSharp):

1. string playerName = await AuthenticationService.Instance.GetPlayerNameAsync();
2.  
3. playerName = string.Join("", playerName.SkipLast(5));

 

No need to remove because there must be a duplicate name then the hash could help player to distinguish their real account.

Like would be pain to distinguish these leaderboard.
1. Carrot
2. Carrot
3. ... etc
