as you can read in this documentation page the open link action should have two sections; URL and Target. In my screen the Target is missing though.
The two options should be Browser and Web View. The link opens by default in a new tab in the browser and instead i want it to open within the app (web view option).
It appears that the functionality of the Open Link action was changed at some point, and the documentation hasn’t been updated.
However to get the functionality that you are after, I think what you could do it use a Set Column Values action to replace the value in the column that your webview component is using.
