Changing cassette from 11-32T to 12-34T - longer chain?

My road bike cassette and chain need replaced so taking the chance to go from 11-32 to 11-34.

Crankset is I think 52/36. This is all 105 r7000 and i have the medium cage rd.

Do I need to make the new chain longer, and if so by how many links compared to the old one?

Thank you!
