I have two issues below that I am trying to resolve. Any helps would be appreciated.
1. I used the formula below to concat the filenames of attachments, but I would like to remove the & at the end.
Concat(DataCardValue57.Attachments,Name & " & ")

2. I use the formula below to send email with attachments but is not working. The error message is "Invalid number of arguments: Received 5, expected 3-4"
Office365Outlook.SendEmailV2( To1_2.Text, Subject1_2.Text,RichTextEditor1, {Cc: CC1_2.Text}, {Attachments: AddColumns(RenameColumns(DataCardValue57.Attachments,"Value","ContentBytes"),"@0data.type","")})
