Power BI Embedded set Language in Sharepoint Online

Hi,

i have Reports in two culturs, de-DE and en-US.

Embed link for SharePoint

When I embed the report in sharpoint online, the srachen doesn't work. It doesn't matter which default language is set in the browser. It also doesn't work with the parameter "?languageid=en-US" at the end of the link.

Securely embed this report in a website or portal (iframe)

if I insert the reoprt as an iframe and specify the parameter "?language=en-US" this works.

Same problem with Embed in Teams.
