I think using Section Access for sheet access is only possible in QlikView.
I think for Qlik Sense you need to set some security rules.
Start with making sure the users you want to give access to specific sheet(s) do not have access to that app or stream in any other way.
Next, create a security rule with the "App object access" template.
See attachment for a suggestion. Can't guarantee it will work, but it at least should get you a step in the right direction.

Here are some steps through which you can implement sheet level security. The steps are the same as given in this link. But just in a more detailed manner.
i) In sheet level security, we have to create a new security rule in the QMC which defines the name of the sheet and the user who should have access to the sheet.
ii) Before creating a new security rule, we have to change the existing default security rule named “Stream” in the “Security Rule” section of the QMC.
iii) In the “Stream-->Advanced-->Condition”, add the following rule at the end:
So the modified security rule will look something like this:
iv) Now, create a new security rule “sheet” with “Resource filter” as “App*” and “Condition” as shown in the screenshot below.
v) Note, here the user_name is “administrator” and the sheet_names which he has access to are “fiscal” and “fiscal_test”. These are the only two sheets for which "Administrator" will have access to.
vi) The following screenshot will give an idea of the description of the newly created security rule “sheet”:
