Updated Answer:
Based on the new requirements I have modified the code, I dont know where to add the wait 1 you had mentioned.
I have chosen an awesome function in the post of Nimphious the link to this function is here
So you need to set three variables to setup the function, The variables need to written in the eval function, refer to the imacros code below, the details explanation of the variables is shown below:
1. characters:
if characters is set to the below character only those characters under the parameter are set.
'a' -> 'abcdefghijklmnopqrstuvwxyz';
'A' -> 'ABCDEFGHIJKLMNOPQRSTUVWXYZ';
'#' -> '0123456789';
2. Max:
It represents the maximum length of the string that can be present.
3. Min:
It represents the minimum length of the string that can be present.

SET !VAR1 EVAL("var characters = '#'; var max = 20; var min = 32;function randomString(length, chars) { var mask = ''; if (chars.indexOf('a') > -1) mask += 'abcdefghijklmnopqrstuvwxyz'; if (chars.indexOf('A') > -1) mask += 'ABCDEFGHIJKLMNOPQRSTUVWXYZ'; if (chars.indexOf('#') > -1) mask += '0123456789'; var result = ''; for (var i = length; i > 0; --i) result += mask[Math.floor(Math.random() * mask.length)]; return result;};var randomString=randomString(Math.random() * (max - min) + min, characters); randomString;")

Old Answer:
You can use this simple macro to insert a random string into the field and click 'Save Changes' every time. If you need to refresh the page, add the commented line also. Dont forget to loop this macro any number of times as per need.
SET !LOOP 1
'URL GOTO=https://EXFESDGT.org/edit
SET !VAR1 EVAL("var randomString=Math.random().toString(36).substr(7); randomString;")
PROMPT {{!var1}}
TAG POS=1 TYPE=INPUT:TEXT FORM=ID:editForm ATTR=ID:customURL CONTENT={{!var1}}
TAG POS=1 TYPE=BUTTON FORM=ID:editForm ATTR=TXT:Save<SP>Changes
