Trying to use restrict property to limit 1st char to 0-5, etc

Hello all you RegEx fiends,

I’m trying to use the restrict property of a TextInput field to limit the entry of minutes, so restricting the number of characters to 2, while restricting the first character to the range [0-5] and the second character to the range [0-9]

I’ve tried a billion things, but I’m not sure I’m going about this the right way, any advice?

Thanks!
