How do I know if my purchases are being recorded and how to view them?

From what I believe, I have implemented the DataStore and PurchaseHistory correctly to record the transactions that are purchased from my developer products. How would I be able to verify it's working and also is there a way to view those transactions?

Here is my script for verification. Any help would be appreciated.

local mpService = game:GetService("MarketplaceService")
local PurchaseHistory = game:GetService("DataStoreService"):GetDataStore("PurchaseHistory")

mpService.ProcessReceipt = function(receiptInfo)
    local playerProductKey = receiptInfo.PlayerId .. ":" .. receiptInfo.PurchaseId
    if PurchaseHistory:GetAsync(playerProductKey) then
        return Enum.ProductPurchaseDecision.PurchaseGranted
    end

    local plr = game:GetService("Players"):GetPlayerByUserId(receiptInfo.PlayerId)
    if not plr then
        return Enum.ProductPurchaseDecision.NotProcessedYet
    end

    if receiptInfo.ProductId == 55131820 then
        local Lives = plr.leaderstats.Souls;
        Lives.Value = Lives.Value +1
    elseif receiptInfo.ProductId == 55131892 then
        local Lives = plr.leaderstats.Souls;
        Lives.Value = Lives.Value +5
    elseif receiptInfo.ProductId == 55131917 then
        local Lives = plr.leaderstats.Souls;
        Lives.Value = Lives.Value +10
elseif receiptInfo.ProductId == 55131947 then
        local Lives = plr.leaderstats.Souls;
        Lives.Value = Lives.Value +15
elseif receiptInfo.ProductId == 55131997 then
        local Lives = plr.leaderstats.Souls;
        Lives.Value = Lives.Value +25
    end

    PurchaseHistory:SetAsync(playerProductKey, true)    
    return Enum.ProductPurchaseDecision.PurchaseGranted     
end
