find & replace ms word 2016

Hello
I have the following working script:

set findRange to find object of selection
tell findRange
clear formatting
clear formatting its replacement
execute find find text “searchString” replace with “replaceString” replace replace all
end tell

The problem is that it do not replace the Text in the header, the footer, or in a tablecell of the Word-Document. Is there a Way to replace all “ not only the Text in the body?
Many thanks in advance for your efforts!
