How can i redirect /?lang=en|ru to /?lang=en#googtrans(en|ru)?

How can I add the Google translate parameter #googtrans(en|de) or other language, so the translation happens automatically?

Basically, when the user goes to https://example.com/page/?lang=de they are redirected to https://example.com/page/?lang=en#googtrans(en|de)

I use this .htaccess rule, but it's not working:

RewriteCond %{QUERY_STRING} ^lang=([a-z]{2})$
RewriteRule ^/?lang=en#googtrans(en|[a-z]{2}) [R=301,L]
