I don’t believe it’s possible to find a selector using a Contains operator.
However, you can use the wildcard "*"
So basically, it will find any selector where any text appears in the wildcard.
Using your selector, it would look like:
The “*” will tell it to find any selector where there is text infront of the word ServiceNow
To take this a step further, you can also use variables inside the selector if you want this to be more dynamic. In order to do this you simply click inside the Selector box in the Properties pane on the right (not clicking Edit). Then, edit the selector expression as a string. Once edited, you can click the Edit button and it will bring up the Expression Editor to make it easier.
"< html app=‘chrome.exe title=’*"+variable+"’ / >"
But, for what you are needing, you can probably just stick with the wildcard “*”
EDIT: Additionally, I’ll just add that technically if you want to see if a selector contains text, you can use Find Element then using the element variable retrieve the selector as a string and use str.Contains() in an If condition. That might be useful to know, however, I don’t use it for finding selectors cause variables and wildcards seem to accomplish everything I have seen in business processes.
