Created Unassigned: Read Only setting (?) [9189]

Hello and thank you for the library! I need to read data from an Excel Worksheet and this is totally feasible as long as the file is not open when the following statement is invoked:

var xlWorkBook = new ClosedXML.Excel.XLWorkbook(path);

I understand that when writing in an Excel worksheet it should not be possible to have it opened but what about reading? Is there any "only-reading" setting implemented?

Thank you in advance,
