MS Office Proofing Tools for Hebrew -- (1) grammar-check doesn't work, (2) where to get a good Hebrew dictionary for MS Word

Question

I have MS Office LTSC Professional Plus 2021, running on Windows 11 23H2. I use it to create Hebrew language files in MS Word. As such I want to use the MS Office Proofing Tools (spell- and grammar-check, thesaurus, etc).

So far I have done the following:
(1) Added Hebrew language to Windows Input Methods.
(2) Installed the Hebrew Language Pack for 64-bit Office
https://support.microsoft.com/en-us/office/install-the-hebrew-language-pack-for-64-bit-office-0e7bc753-71de-4996-90b5-1f519d9baf9e?ui=en-us&rs=en-us&ad=us
(3) Confirmed that Hebrew is set as the display language
File > Options > Language > Office display language
(4) Confirmed that Hebrew is set for authoring
File > Options > Language > Office authoring languages and proofing

I can now author Hebrew documents in MS Word 2021 and edit existing ones without any issue. And on the Review menu I can use some of the Proofing Tools (spell-check, thesaurus and translate).

However the Hebrew dictionary that comes with the Hebrew Language Pack seems to be a very rudimentary one. Take for example the Hebrew word for woman. The dictionary recognizes the spelling אישה , but does not recognize the more common spelling of אשה -- which happens to be the spelling offered by GoogleTranslate (https://translate.google.com/?sl=en&tl=iw&text=woman%0A&op=translate) .

At the bottom of the Thesaurus sidebar it says: "Word currently does not have a dictionary installed for Hebrew. To see definitions, {Get a Dictionary}". But when I click on the <Get a Dictionary> link, I am taken to the 'Dictionaries' sidebar where it says: "Install a dictionary from the Office Store to see definitions".

I searched with Google for "MS Word 2021 Hebrew dictionary" but found nothing useful.

ALSO, the grammar-check doesn't seem to work.
For example, it does not flag the following expression האיש אוכלת (the man eats) as being a grammar error. The conjugation is incorrect and it should be האיש אוכל .

So my questions are:
(1) Where do I get a good Hebrew dictionary for use with MS Word 2021?
(2) How do I get the Grammar-Check to work?

Any help, would be greatly appreciated.
