You can add a delay by inserting a delay column between your lookup and the target column. Each delay column adds about 10 seconds, so you'd need to stack 6 delay columns to get close to 1 minute.
Set up the lookup in table A using Actions → Lookup Multiple Rows in Other Table, then add your delay columns before any dependent actions. You can also use the delay column's completion as a run condition for subsequent columns.
For scheduled lookups, you can set up recurring runs, though note that scheduled runs happen every 24 hours from when you first schedule them. [1]
If you need any more help with setting up the lookup table action or the delay, please let me know. Would you like to provide more details about what you're trying to achieve so I can assist further?
