SQL server reporting services 2019 and HSTS headers

Apologies if this is not the correct section to post.

We have SQL Server and SQL Server Reporting Services 2019 installed on a server.  

Per this article, we should be able to modify the custom headers property to enable HSTS

https://docs.microsoft.com/en-us/sql/reporting-services/tools/server-properties-advanced-page-reporting-services?view=sql-server-ver15

What custom header should be used for HSTS to be included in the header for all reports / sites?

I tried 

<CustomHeaders>
<Header>
<Name>Strict-Transport-Security</Name>
<Pattern>\/Reports\*</Pattern>
<Value>max-age=86400</Value>
</Header>
<Header>
<Name>Embed</Name>
<Pattern>(.+)(*)(.+)(rs:embed=true)</Pattern>
<Value>True</Value>
</Header>
</CustomHeaders>

But this did not seem to work.
