[BUG] %MATCH% is not replaced by "whatever triggered the filter"

[yodabird19]

Describe the bug
%MATCH% is not replaced by whatever triggered the filter as stated.

Minecraft Info
fabric loader-0.14.6-1.18.2
fabric-api-0.53.3+1.18.2
AdvancedChatCore-1.18.2-1.5.0
AdvancedChatFilters-1.18.2-1.2.3

To Reproduce
Attempt to use %MATCH% in a filter's "Replace to" field.

Expected behavior
%MATCH% would be replaced by the text that triggered the filter.

Screenshots

An example filter attempting to use %MATCH%

Rollover text instructing me on how to use %MATCH%

The behavior of the example filter above, in which %MATCH% is replaced literally rather than with the text that triggered the filter

Additional context
I also tried "%Match%", "%match%", and "MATCH", none seem to work.

Thanks in advance for your help, this is a great mod! I hope this bug can be fixed soon.

very late but when the type is set to regex you can use $0 (or wrap the desired fragment in brackets to mark a group and use $1)
doesn't work in literal/upper-lower sadly (even though #14 still happens with $1)
