+
+ MATRIX_SERVER The name or base address of the Matrix server to

+ ROOM_ID The Room ID can be found in the URL of the room
+ usually following format '!123123123:matrix.org'.

+ NOTE: Single quotes are very important here.
+
+ WANTED_TAGS A space separated list of valid tags to find posts

+ Default is \"$WANTED_TAGS\"

+ MAX_REPLIES Filter for posts that have less than or equal to
+ this many replies. Default is \"$MAX_REPLIES\"
