Monitoring blood pressure

[Galaxi4]

Hello

Is there a step by step guide to set up my Galaxy Watch4 to monitor my blood pressure?

The measurements I need are:

1) every hour including during sleep

or

2) one in the morning and one in the evening

However, I need it to take two measurements one after 10 seconds from the other (for verification).

Any advice please? Unfortunately the app/watch are not very intuitive.

Thanks!
