Your shop is indexed and a search within your shop for 'sticker' brings up your tea pot listing. However, it does not show in an Etsy search despite using the exact term 'sticker pot of tea' and after narrowing down the results to recency and France location.
Everyone does get different search results and it also can be that your listing is very new and may appear soon. I would suggest, however, to add tags to your listing which helps buyers find your sticker in a search.
(That was an interesting translation of your post! I had to use google translate to see the correct word it suggested. Is there a typo in your post?)
