Hi @Anonymous,
You could use the Get file content action of OneDrive connector to get the file you want to send as an attachment. There is the screenshot that sends one file:

If you want to send multiple files, you could initialize an array variable and use append to array variable action to store these files content:

After appending to the variable, put it into the Attachments field, then you could send these files by email:
