SOLR Fuzzy search for part of words

Question

first of all i've no rights to edit the schema because the client uses a hosted solr.

i try to finde the following word:

Coagulometerröhrchen

with this query:

&q=(röhrchen~)&defType=edismax

When i try to use the query like this:

&q=(*röhrchen*~)&defType=edismax

it's missing some keyresults

Is there a way to find the right results with a optimized query?

Solr-Version: 8.11.1
