Data Manipulation through built-in functions

I want to change Variables through built-in function (replace)

I want to put a comma between the every collected digits by called user.

ex.)

  • “$(cbPhoneX)” is collected digits by called user.

→ =replace("$(cbPhoneX)", “???”, “???”, “ig”)

=replace("$(cbPhoneX)", “”, “,”, “ig”)

Not sure “” would match anything.
In case it doesn’t:

=replace("$(cbPhoneX)", “(\d)”, “\1,”, “ig”)

Thank you for replying
