Finally I ended using (it's also working for different languages of Recaptcha challenges) if someone searches for the same:
">CSS>iframe[src^=' https://www.google.com/recaptcha/api2/bframe ']>FRAME> >CSS>#recaptcha-verify-button"
Initialise
Set Variable No-of-Cycle
For 1:No-of-Cycle
Call Function 1
Set Variable No-of-Times
For 1:No-of-Times
Call Function 2
Call Function 3
Increase Variable 1->No-of-Times
Sleep 30 minutes
Increase Variable 1->No-of-Cycles
Sleep 30 minutes
During running of the cycle/times, how to clear cache?
Use RESET option in BROWSER TAB . this will clear cookies but cache will be still present. You can also make a profile and save it for further use. Let us know if this works for you.
