[Security:Assets:Fleet:AgentPolicy:Edit Integration page]Grouping issues with radio buttons, checkboxes

[L1nBra]

Description
Elements should be grouped programmatically the same as visually for the users using assistive technology for better understanding.

Preconditions
Security -> Assets -> Fleet -> Agent Policy -> Edit Integration page.
Switch buttons on Panel components are on (like: Ransomware protections, Memory threat protections...).
Use Screen Reader (NVDA).

Steps to reproduce

1.Using only keyboard navigate through radio buttons on the page.
2.Observe page and screen reader.
3.Using only keyboard navigate through checkboxes on the page.
4.Observe page and screen reader.

UI elements + NVDA Speech Viewer
radio buttons

checkboxes

Actual Result

• Radio buttons are announced as "...of 11" - total number is from all the radio buttons on the page. User can navigate through radio buttons by pressing right arrow key (in this case user skips all other elements on the panel and is not aware about them).
  All checkboxes are treated individually, without group announcement.

Expected Result

• On the page visually panel components are separate. And each panel has its own elements. One panel has only 2 radio buttons. Would be better if screen reader user, when navigates to radio buttons on the panel, hears correct total number of radio buttons (radio button number per panel not per page) and could navigate with arrow keys only between radio buttons on the panel.
  On the panels which have Events section, visually it is clear that checkboxes are for events. Would be better if screen reader user upon reaching these checkboxes would hear that they belong for the group (similar when user reaches expandable button and when expands it and navigates to first element - expandable button is announced, grouping announced, then the first element announced. Other elements are announced as elements without repeating grouping in the same group when navigating to them).
