Mod_rewrite - redirect query string to homepage

Question

Can you help me redirect this url https://www.theholisticsanctuary.com/?s=%7Bsearch_term_string%7D to homepage using htaccess? I tried it using rank math redirect but no luck. I have tried this but Im afraid it is wrong.

<IfModule mod_rewrite.c>
  RewriteEngine On 
  RewriteCond %{QUERY_STRING} ^s=%7Bsearch_term_string%7D
  RewriteRule ^https://www.theholisticsanctuary.com/? [R=301,L]
</IfModule>
