Phone number converter

We are using Zapier and I need phone number string converter to our fixed mask.

Code can be in Javascript or Python.

We have different forms across our websites and we are asking people to insert their numbers.

sually people insert their phone numbers in that style:

031222333
031 222 333
031-222-333
031 - 222 - 333
31 222 333
31-222-333
+386(0)31222333
+386 (0) 31 222 333
0038631222333
00386 31 222 333

or even in any other style.

I need to be output exactly like this: +38631222333

+386 - is fixed string and it's our country code
31 - are first three digit of number, but 0 shouldn't be there
222 and 333 are last 6 digits of phone number

I will provide you Zapier login and test environment.
