Best helper to prompt for time duration?

I flashed few Tuya smart sockets with Tasmota FW and integrated them into HA.
In doing so I lost the ability to add countdown timer to sockets.

I wrote a script to turn the socket off after countdown, but I’m struggling with which helper to use to prompt for hours, minutes and seconds?
If I use time, I am missing seconds, and I get an additional unrelated AM/PM field, plus hour field is max 12. Clearly not meant for this purpose.

I imagine such helper could be used whenever you want to ad hoc delay or prolong certain action.

Having an input number in seconds is not really an option as it becomes illegible beyond few minutes.

Any suggestions?

I don’t quite understand, how showing timer helper entity card enables me to enter duration in hours / minutes / seconds?
