LibreOffice Base how to use edit mask for an email address?

I am currently building a database for my customers and their purchases in LO Base v6.2.4.2. I would like to use the pattern field and the edit mask for the input of an e-mail address. I am finding that the edit mask works wonderfully when the length of characters is known. However, e-mail addresses are far more variable. Is there any way to use the edit mask for e-mail addresses? I would rather not use a macro, if possible. Any assistance would be helpful.

Thank you in advance,



Unfortunately it appears that uses fixed length only.
