Repeat Until Function for Events module

Hi guys!

I would like some help!
I searched here on the forum on the subject, but I would like to be sure.

I inserted the ‘radio’ button of the events module in the popup of the calendar module.
However, I would like the ‘repeat until’ option also appears for this module.

I found the TPLS files and added them to the event module, but I can’t seem to make these options appear.

Has anyone been through something like this?

I am grateful if someone indicates at least the files that I should modify.
