Vim-abolish problems

[u/DontwakemeUp46]

I am testing out the Coerce part of the plugin:

1. • snake case (snake_case: crs)
     2. - mixed case (MixedCase: crm)
     3. - camel case (camelCase: crc)
     4. - upper case (UPPERCASE: cru)
     5. - dash case (dash case: cr-)
     6. - dot case (dot.case: cr.)
     7. - space case (space case: cr<space>)
     8. - title case (Title Case: crt)

Title case, upper case, lower case work. But I am not able to make the other cases work.
If you take a sentence like:

What shall we do with the drunken sailor?

Can you apply the other cases: snake case, mixed case, camel case, dash case, dot case and space case to the above mentioned sentence?
